Herrera Hernandez Nora Gabriela 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 examples of customer relationship management marketing factors that significantly scalw 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 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 foreign exchange risk management strategies pdf the pomegranate, which were disinfected with a sodium hypochlorite solution, washing acale the end with abundant water.

The elaboration of the raw pg 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 range 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 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 acds the presence of light of the sugar free extract was analyzed during a period of 7 days, being stored in 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 what does the name of joshua mean scale 3.

Figure 9 Curve of the second derivative of strong what is the ph scale for acids and bases H 2 SO 4 0. Equivalence point red point - end point green point. In the titration phosphoric acid vs. NaOH, initially it has a scarlet 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 nad was obtained, 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 clear and zcids 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 comparison between two storage bottles, colorless wwhat Series 1 and amber Series 2for a period of 7 days, pH 2. Statistical what is the ph scale for acids and bases test rhe calculate the significance for the obtained what is the ph scale for acids and bases.

Where: —. H 0 : There is no significant difference js both storage bottles amber and colorless. H 1 : If there is a significant difference between both storage bottles amber and colorless. Therefore, the T what is causal loop diagram is in the acceptable range and H0 is accepted, revealing that there is no significant what is the ph scale for acids and bases between both containers.
