(a) Interpretation: The pH at the equivalence point for the titration of 0.10 M solutions of HNO 2 and NaOH and suitable indicators for the titration should be determined. Concept introduction: The equivalence point is the point at which the moles of the titrant added is completely neutralized the analyte solution or the point at which the moles of acid equivalent to the moles of base. Indicators are the substances that change the color according to the pH of the mixture and help to visually identify the equivalence point which is called the endpoint.

Concept introduction:
The equivalence point is the point at which the moles of the titrant added is completely neutralized the analyte solution or the point at which the moles of acid equivalent to the moles of base. Indicators are the substances that change the color according to the pH of the mixture and help to visually identify the equivalence point which is called the endpoint.
Interpretation Introduction
(b)
Interpretation:
The pH at the equivalence point for the titration of 0.10 M solutions of HI and NaOH suitable indicators for the titration should be determined.
Concept introduction:
The equivalence point is the point at which the moles of the titrant added is completely neutralized the analyte solution or the point at which the moles of acid equivalent to the moles of base. Indicators are the substances that change the color according to the pH of the mixture and help to visually identify the equivalence point which is called the endpoint.
