Interpretation Introduction

Interpretation: Concentration of ${\text{H}}_{\text{2}}{\text{C}}_{\text{2}}{\text{O}}_{\text{4}}$

Conceptual Introduction: ${\text{H}}_{\text{2}}{\text{C}}_{\text{2}}{\text{O}}_{\text{4}}$ is the formula of oxalic acid. Oxalic acid is a colourless solid. It forms transparent solution in water. It is a diprotic acid. It dissociates in two steps.

Solutions: First we will calculate ${\text{H}}^{\text{+}}$ concentration. From ${\text{H}}^{\text{+}}$ ion concentration, pH value of the acid can be calculated. Putting the value of pH in Henderson equation we can calculate the concentration of acid.
