Chapter 17, Problem 70E

Interpretation Introduction

Interpretation:

If the value of $\text{pBr}$ is $\text{7}\text{.2}$, then the concentration of bromide ion is to be calculated.

Concept introduction:

Concentration of a species can be expressed in different ways. Very low concentrations are usually expressed as logarithm of base $10$. Logarithm of base $10$ is written as $\text{p}$. Value of $\text{pX}$ is written as $-{\log }_{10}\text{X}$.
