Chapter 16.10, Problem 16.18WE

Interpretation Introduction

Interpretation:

The pH of the given aqueous solutions has to be calculated.

Concept Introduction:

The relation between equilibrium constants $K_a$, $K_b$ and $K_w$ is,

$K_b=\frac{K_w}{K_a}$

The concentration of hydroxide ion is measured using $\text{pOH}$ scale. The basicity of aqueous solution is expressed by $\text{pOH}$ scale.

The $\text{pOH}$ of a solution is defined as the negative base-10 logarithm of the hydroxide ion concentration.

$\text{pOH}\text{=}{\text{-log[OH}}^{-}\text{]}$

The relation between pH and pOH is,

$pH=14-pOH$
