The rapid change of pH near the stoichiometric point of an acid-base titration is the basis of indicator detection.pH of the solution is related to ratio of the concentrations of the conjugate acid (HIn) and base (In⁻) forms of the indicator by the expression
Options
(a) log [In⁻] / [HIn] = pKIn – pH
(b) log [HIn] / [In⁻] = pKIn – pH
(c) log [HIn] / [In⁻] = pH – pKIn
(d) log [In⁻] / [HIn] = pH – pKIn
Correct Answer:
log [In⁻] / [HIn] = pH – pKIn
