Herrera Hernandez Nora Gabriela 1. Borquez Jorge 2. The research proposes to obtain a natural acid-base indicator from strongg 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 ajd significantly affected the color of the extract of the Punica granatum L.

The analytical chemistry uses synthetic indicators in order to verify the stfong of pH according to the color variation, currently these valuation processes do not abd natural indicators, generating inconveniences in what is the ph of strong acid and strong base response produced by the discharge and response processes, a negative impact on what is the ph of strong acid and strong base environment environment 157.

Anthocyanins to red increases 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 3presenting 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 out to obtain the arils of the 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, ; press 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 what is the ph of strong acid and strong base of 3. In the UV-Vis Spectrophotometer Spectroquant Pharo the wavelength displacement was analyzed as a function of the pH variation of the buffers previously discussed, in bae 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 off during a period of 7 days, being stored sttrong an amber glass bottle 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 that assumes that the sample variances are equal and another version that does not assume 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 buffer scale at pH 3. Figure 4 pH scale 3. Figure 5 Variation of wavelength as a function of pH variation. The pH scale 3. Figure 6 Absorbance of different values of the pH scale, in different fractions of time 0, 5, 10 and 15 minutes. Use of Punica granatum L extract as a pH indicator in potentiometric titrations.

In the what does muddy mean in nyc slang HCl vs NaOH, initially it has a scarlet red color, that when arriving at the end point to neutral green point a yellow color is observed, with an expenditure volume of 30mL at a pH of 8. Equivalence point Red point - End point Green point. In the titration CH3COOH vs NaOH, initially it has a pink color, that when reaching the final point or neutral green point a yellow color is observed, which was given at a volume of With 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 SO 4 0. Equivalence point red point - end point green point. In the titration phosphoric acid vs. NaOH, initially it has ahat what is the ph of strong acid and strong base red color, that when reaching the first end point or neutral green point the end point is observed a yellow color which was given at a volume of 26 mL and a pH 8.

With the previous results, the equivalence point was obtained, being 20 mL red point. Figure 10 What is class ii division 1 of the second derivative of strong acid H 3 PO 4 0. From the spectrophotometric study wbat the indicator, it was necessary to select a region of the scale where there is a clear 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 oxygen and light from the extract Punica granatum L. The study of the stability of the extract of the fruit Punica 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 hase between two storage bottles, colorless glass Series 1 and amber Series 2for a period of 7 days, pH 2.

Statistical t-Student test to calculate the significance for the obtained data. Where: —. H 0 : There is no significant difference what does impact mean in early years both storage bottles amber and colorless. H 1 : If there is a significant anc between both storage bottles amber and colorless.

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