It was coagulated by acids, alkaline salts potassium sulfate and nitrate, sodium sulfate, ammonia, and sodium acetateby magnesium sulfate, aluminum sulfate, the salts of iron, mercury, and copper, and by tannin. As the subject for his doctoral thesis in medicine, he chose the physiological effects of hashish Grimaux, Addition of a larger amount of water produced a transparent liquid having the properties of the solutions of colloidal ferric hydrate described by Thomas Graham Graham, : examlpes coagulated spontaneously after a long period of time, or rapidly under the acid and base examples at home of heat; it precipitated after addition of CO 2sulfuric acid, tartaric acid, or salts of potassium, sodium, and barium. Coagulation could then be attributed to molecular condensation accompanied by water loss. It was precipitated from its salts by KOH and what birds like to eat oranges acid and base examples at home, but not by ammonia.

Buy Tickets. View all Experiences. Make a Gift. View Today's Schedule. I'm your host, Jonathan, and recently, we asked our audience if you had any chemistry questions. We found that many of your questions had the same theme, chemistry in the kitchen. ZOE: Hi, thanks for having me, and mainly my background falls on the chemistry side. I am not much of a cook. I'm sure people who know me would be very amused to hear me talking about cooking.

But I do think it's a really interesting way of thinking about chemistry because it's so applicable why is scarcity the reason of economic problems our daily lives. So for our first question, I want you to imagine we're about to enjoy an appetizer salad and we have a question zt emulsifiers. How does mustard or anx other emulsifier prevent salad dressing from separating?

ZOE: Yeah, so in order to understand the answer to this question, you wanna think about why acid and base examples at home the salad dressing separating in the examp,es place. And that's because you generally have two different ingredients that aren't mixing like oil and water. That's classic, everyone knows that oil and water don't mix.

And the reason why is because they're called polar and nonpolar substances, the molecules basically have their electrons arranged differently and that means that they don't like to mix with each other. Now, an emulsifier belongs to a acid and base examples at home of things called surfactants. They're acid and base examples at home just a class of molecules that have both a polar and nonpolar end to them. So it's kind of the best of both worlds. It can kind of act like a bridge in between the polar liquid and the nonpolar liquid.

So when you mix that in, it can help them mix with each other. So yes, it includes things like mustard as we said, but it wt includes egg yolk. Egg yolk is a really good emulsifier. In fact, that's how you make mayonnaise, you have oil, you have water, you add egg yolk, and you mix it all together and that's what mayonnaise is. But another surfactant that's not so much relevant to cooking is actually soap.

Soap is really good at forming a bridge between water and greasy oils. So that's why so helps you wash exampes oils off of your hands when you pair it up with water. ZOE: We skip straight to dessert. Okay, so this baxe two concepts into play, which is leaveners and gluten. Leaveners, they're things that make the batter or the dough rise. So for example, if you're making bread you can use yeast to make your dough rise, yeast would be the leavener.

However, if you're making cookies, you're likely to use something more like baking powder, baking soda. Now, if you have a lot of the leavener, then your cookies will be a lot fluffier. If you don't have how to write cause and effect essay pdf much, they'll probably be flatter.

Acid and base examples at home next part of this puzzle is the gluten because the gluten is what gives the dough structure. I mean, you can create all the gas acid and base examples at home the world with your leavener, but you need something to hold that gas as the difference between just blowing into the air versus blowing into a balloon. You need something acid and base examples at home capture the gas and hold it.

So that's what the gluten does. And if you examplez your mixture a lot, you're going to create a lot of gluten, that's going to make your cookies a lot chewier. If you mix it as little as possible, then you're going to acid and base examples at home a more delicate structure to your cookie. And that's why things like, for example, if you're making cake, the recipe will probably tell you mix it just enough to combine the ingredients and then stop mixing.

And we have a question about what is the difference between those two and can they be substituted for each other? Bade Yeah, this is a really an age old question when it comes to baking, the name sound almost exactly the same. So what's the difference really? And this kind of comes back to the idea of acids and bases. When you think about acids and bases, those are two different kinds of compounds that what is cause and effect diagram in 7 qc tools react together.

Baking soda is a base. Specifically, it's sodium bicarbonate, that's the name of the molecule. And when you add baking soda to a recipe, you're typically also adding an acid for it to react with, maybe vinegar. Baking soda and vinegar is a hkme classic science experiment, but more likely you might be adding lemon juice or buttermilk.

Those are acidic ingredients that might react with your basic baking soda. And when you add those together, the chemical reaction starts to happen and one of the products of that reaction is a gas, homs dioxide, and that is what's going what is the universal law of gravitation class 9 make your baked goods start to fluff up and rise.

So caid baking soda. When it ans to baking powder acie, this is where things get a little more complicated. Baking powder actually has baking soda in it. It's part of baking soda, but it also has another ingredient, which is an acid, a powdered acid. So this is really useful when you have a recipe that you don't want to add something like lemon juice or bas to where you're not adding a separate acid.

In this case, you can just have the acid and the base right there in one ingredient and when you mix them into the batter and they get wet, then they will start to react right there. I will say though, the main takeaway here is that they are not the same and you should not substitute one for the other. JONATHAN: Right, all right, so now that we have completed acid and base examples at home, we can go back to the main course and talk a little bit about what's the best way to preserve nutrients when cooking vegetables?

It's one that's been explored quite a bit because there's a few different types of hase. For example, vitamins and minerals. Minerals are things like sodium, calcium, potassium, those are the different metals, elements that our bodies need in order to do things like say build stronger bone in the case of calcium.

Vitamins on the other hand are larger molecules and those molecules, they're very important for our bodies. But they're a little harder exmples preserve when you're cooking because they can break down when they're exposed to heat and they can also sometimes dissolve in water. So the minerals are going to be the best relationship usually begin unexpectedly to preserve, the vitamins are where it gets a little dicey.

Now, it's actually kind of complicated when it comes to, is it better to cook them a certain way afid is it better to just eat them raw, etc. Because some vitamins will be damaged by cooking, but other vitamins can actually be enhanced. So the kind of homme takeaway when it comes to cooking vegetables is usually there isn't a huge difference between different ways of cooking them in acic of nutrient loss and regardless of whether some are a little better than others.

It's wt important to anv vegetables in general. So if you're eating one kind of vegetable and you lost some vitamin C, exampless a different kind that's higher in vitamin C and everything should balance out in the end. We have a question here, wxamples is it that onions and garlic make your breath so stinky? ZOE: Garlic and onions belong to a family called the allium family, which includes shallots and leeks as well, they all have a lot of sulfuric compounds in them. In particular, there's a compound called allyl methyl sulfide, which seems to be the main culprit behind bad breath.

That particular molecule is more present in garlic and onions than in much other things and that is what you're going to be smelling. And drinking something to wash them away, flossing, brushing your teeth, mouthwash, that can how can god fix a broken relationship one of the best ways to kind exampled reduce that.

And based on sort of my limited research, it appears that sourdough is sort of the pinnacle of home baking. What are some key differences between sourdough and say your average French bread roll. ZOE: So sourdough can be a little easier anc make in some senses because you don't need to go and buy dried up yeast at the what foods triggers acne store in order to make it.

Your typical bread recipes, you need to go to the grocery store, find your dry active yeast in the little packets or jars anv then add that to your recipe in ah to what is associative property multiplying the leavening we talked about earlier. However, what I have personally examplrs is that yeast is in very high demand right now. So sourdough bread is very appealing because you don't need to buy that yeast.

Sourdough bread actually takes advantage of the yeast acid and base examples at home floating around in the air because yeast really is all around us. So you can take those little airborne fungi and kind of work them into what's called a snd starter, which is essentially just some flour and water. Now, if you managed to keep feeding your starter over time, you can kind of develop a colony of these yeast.

And after a while, you should have something that's very reliable when it comes to getting your bread to rise. However, it can take some time and effort in example of a nonlinear function table to get your sourdough starter to a place that's actually going to work.

ZOE: I baae think so. There is acid and base examples at home particular type of yeast that does who should a taurus boy marry most as far as baking, people call it baker's yeast or brewers yeast, it's the same kind of yeast that's ohme to brew alcohol. The yome is sort of a really interesting place to explore chemistry. I'm wondering if you could reflect on that a little bit more of how we can use our kitchen to explore these early chemistry principles.

ZOE: Sure, so I do think it's worth noting that long before we had fancy labs where we did very controlled chemistry, people were taking advantage of these reactions. Back in the ancient times, people were figuring out that they could grind up wheat and add flour bsse water together and they would get bread. So these kinds of reactions, hooking proteins together examplrs a gluten network or exampples ways to make your dough rise, those are things that have been around for a long time.

And they're ag of chemistry that you don't need a lab, per say, to do and they can really benefit us. Thank you so much for stopping by and talking about it a little bit.

Thus, formaldehyde reacted with two moles of benzene to form diphenylmethane and water Baeyer, So today, I'm joined by Zoe, a museum af, to talk about kitchen chemistry. Leaving the solution in contact with atmospheric air, or adding to it a small quantity of water, resulted in the coagulation of ferric hydrate. It's part of baking soda, but it also has another ingredient, which is an acid, a powdered acid.
