Chapter 14, Problem 122MP

Interpretation Introduction

Interpretation: The volume of $0.100\text{M}$ ${\text{HNO}}_{\text{3}}$ that must be added to the given mixture to achieve a final $\text{pH}$ value of $7.21$ is to be calculated.

Concept introduction: The $\text{pH}$ value is defined as a figure that is used to express the acidity or basicity of a solution by using the logarithmic scale on which 7 is a neutral. The values lower than 7 shows acidic or greater than 7 shows basic behavior of the solution. Molarity is defined as the number of moles of solute dissolves in a liter of solution.

To determine: The volume of $0.100\text{M}$ ${\text{HNO}}_{\text{3}}$ that must be added to the given mixture to achieve a final $\text{pH}$ value of $7.21$.
