Chapter 13, Problem 7RQ

Interpretation Introduction

Interpretation: The difference between monoprotic acid, diprotic acid, triprotic acid, $\text{pH}$ calculation of ${\text{H}}_2{\text{SO}}_4$ , reactions referring to $K_{{\text{a}}_1},K_{{\text{a}}_2}$ and $K_{{\text{a}}_3}$ equilibrium constants , $\text{pH}$ calculation of polyprotic acid

Concept introduction: Acids are distinguished based upon their number of protons. ${\text{H}}_2{\text{SO}}_4$ is a diprotic acid. Each successive step of equilibrium of proton donation is written in stepwise-equilibrium constant form. For polyprotic acid we consider stepwise-equilibrium constant.
