Interpretation Introduction

Interpretation:

The best diagram that represents the ions remaining in the solution at the equivalence point in the given titration is to be determined.

Concept Introduction:

The equation for the redox titration of vitamin $\text{C}$ with iodine can be represented as follows:

${\text{C}}_{\text{6}}{\text{H}}_{\text{8}}{\text{O}}_{\text{6}}\left(aq\right)+{\text{I}}_3{}^{-}\to {\text{C}}_{\text{6}}{\text{H}}_6{\text{O}}_{\text{6}}\left(aq\right)+3{\text{I}}^{-}\left(aq\right)+2{\text{H}}^{+}\left(aq\right).$

A titration consists of a redox reaction between the analyte and the titrant, which is known as redox titration. It involves a redox indicator or a potentiometer.
