Chapter 15, Problem 114QRT

Interpretation Introduction

Interpretation:

The volume of hydrochloric acid at standard temperature and pressure that must be added to reduce the $\text{pH}$ of the solution by one unit has to be determined.

Concept Introduction:

Molarity is defined as the ratio of number of moles of solute to the volume of solution is liters.  The S.I. unit if molarity is molar and it is represented by $\text{M}$.

Mathematical formulation of molarity is shown as follows:

  $\text{Molarity}=\frac{\text{Moles of solute}}{\text{Volume of solution }\left(\text{L}\right)}$

The $\text{pH}$ of a solution is the negative logarithmic of hydrogen ion concentration in the solution.  Mathematically it can be represented as follows:

  $\text{pH}=-\log \left[{\text{H}}^{+}\right]$
