Chapter 18.5, Problem 18.9BFP

Interpretation Introduction

Interpretation: Given the concentration of the solution, the equilibrium values of $\left[{\text{H}}_{\text{2}}{\text{CO}}_{\text{3}}\right]$ , $\left[{\text{HCO}}_{\text{3}}{}^{-}\right]$ , $\left[{\text{CO}}_{\text{3}}{}^{2-}\right]$ and also the pH has to be found out.

Concept Introduction: ${\text{H}}_{\text{2}}{\text{CO}}_{\text{3}}$ will dissociate very little because ${\text{H}}_{\text{2}}{\text{CO}}_{\text{3}}$ has a small value of ${\text{K}}_a$. The pH scale will range from 1-14. pH is the negative logarithm of hydrogen ion concentration. If pH is greater than 7 then the solution is basic, less than 7 then the solution is acidic and if it is equal to 7 the solution will be neutral. pH and pOH are related by the equation:

pH + pOH =14
