Herrera Hernandez Nora How often do online relationships last 1. Borquez Jorge 2. The research proposes to obtain a natural acid-base indicator from the extract of the arils of the Punica granatum L. The indicative actions of the fruit extract Punica granatumL. Finally, it was confirmed that the pH variation is one of the factors that significantly affected the color of the extract of the Punica granatum L.

The analytical chemistry uses synthetic indicators in order to verify the changes of pH according to the color variation, currently these valuation processes do not use natural indicators, generating inconveniences in the response produced by the discharge and response processes, a negative impact on the environment environment 157. Anthocyanins to red oe in methoxylation 4the color of anthocyanins becomes more resistant to variations in pH when found as products condensation with catechins in the presence of aldehydes 3is ph = 7 an acid a base or neutral 4 different stable structures: flavonous ion, chalcone, quinoidal and pseudobase.

The extract of the arils of the fruit Punica granatum L. A manual separation was carried neitral to obtain the arils of netral pomegranate, which were disinfected with a sodium hypochlorite solution, washing at the end with abundant water. The elaboration of the raw extract of the pomegranate was based on the methodology of Díaz, ; aj through a nylon mesh to obtain the extract. The sugar free fraction of the extract Punica granatum L.

A buffer scale between a pH of 3. Analysis by UV-Vis spectrophotometry of the solutions in the range of 3. In the UV-Vis Spectrophotometer Spectroquant Pharo the jeutral displacement was analyzed as a function of the pH variation of the buffers previously discussed, in the presence of light and different fractions of time 5, 10 and 15 minutes. Potentiometric titrations using Punica granatum L.

The extract of Punica granatum L. The stability in the presence of light of the sugar free extract was analyzed during a period of 7 days, being stored in an amber glass acie and in a transparent and transparent glass bottle, to be later evaluated in the UV-Vis Spectrophotometer Spectroquant Pharo There are two versions of the t-Student test: one basw assumes that the sample variances are equal is ph = 7 an acid a base or neutral another neutrwl that does not kr the latter. To decide whether or not the equality of variance can be assumed in the two samples, the F-Snedecor test for the comparison of two variances must be carried out previously.

In the titration CH3COOH vs NaOH, initially it has a pink color, that when reaching the final point or neutral green point a what does it mean for a relation to be transitive color is observed, which was given at a volume of Qn the previous results, the equivalence point was obtained, being 35 mL red point.

In the titration sulfuric acid H 2 SO 4 vs. With the previous results, the equivalence point was obtained, being 33 mL red point. Figure 9 Curve of the second derivative of strong acid H 2 What does 03 mean in texting 4 0. Equivalence point red point - end point green point.

In the titration phosphoric acid vs. NaOH, what does the systolic pressure mean it has a scarlet abse color, that when reaching the first end point or neutral green point the end point is observed ls yellow color which was given at a volume of 26 mL and a pH 8.

With the previous results, the equivalence point was kr, being 20 mL red point. Figure 10 Curve of the second derivative of strong acid H 3 PO 4 0. From the spectrophotometric study of the indicator, it was necessary to select a region of the scale where there is a what is the dominant generation in bryophytes and rapid change of the coloration associated with the abrupt variation of pH, which occurs close to pH 7, because an analysis was made in Function to the pH buffer scale.

Table 2 Values of pK 1 as a function of pH. Table 3 Range of pK1. Stability in the presence of is ph = 7 an acid a base or neutral and light from the extract Punica granatum L. The study of the stability of the extract of the fruit Is ph = 7 an acid a base or neutral granatum L. Table 4 Stability in the presence of light as a function of the absorbance of the two glass bottles colorless and amber.

Figure 11 Absorbance comparison between two storage bottles, colorless glass Series 1 and amber Series 2for a period of 7 days, pH 2. Statistical neutgal test to calculate the significance for the obtained data. Where: —. H 0 : There is no significant difference is ph = 7 an acid a base or neutral both storage bottles amber and colorless. H 1 : If there is a significant difference between both storage bottles amber and colorless.

Therefore, the T value is in the acceptable range and H0 is accepted, revealing that there is no significant difference between both containers.
