Chapter 15, Problem 15.11QP

Interpretation Introduction

Interpretation:

What is meant by the $\text{pH}$ of a solution has to be defined and two ways of measuring $\text{pH}$ has to be proposed.

Concept introduction:

$\text{pH}$ is an logarithmic expression to express a solution is acidic, basic or neutral.  $\text{pH}$ scale lies values between 1-14 and on which 7 is neutral, below 7 values are more acidic in nature and above 7 values are more basic in nature.

${\text{pH = -log}}_{\text{10}}\text{c}$

Where, c is hydrogen ion concentration in moles per liter.
