Answer 2

Indicator that used in the estimation of Amide:

Explanation:

• Indicator:A pH indicator may be a halochromic matter added in small amounts to an answer that the pH of the answer will be determined visually. Hence, a pH indicator could be a chemical detector for hydronium ions or hydrogen ions within the Arrhenius model.

• Phenolphthalein is mostly used as a visible endpoint indicator; it gives a pink-colored endpoint. Total acidity is determined by using 0.1 NaOH (or 0.3125 N NaOH) for an oversized number of samples (Ting and Rouseff, 1986).

• The end point of a titration is that the point at which the indicator changes color. When phenolphthalein is that the indicator, the tip point are going to be signified by a faint pink color.
• Hence C is that the correct option.
• Phenolphthalein is employed because the indicator is employed in theestimation of amide.
