Chapter 21, Problem 78PS

Interpretation Introduction

Interpretation:

The $\text{pH}$ of a $0.10\text{M}$ solution of $\text{NaClO}$ and the concentration of $\text{HClO}$ has to be given.

Concept introduction:

The $\text{pOH}$ is a measure of Hydroxide ion concentration and $\text{pH}$ is a measure of Hydrogen ion concentration.

$\text{pOH}=-\text{log}\left[{\text{OH}}^{-}\right]$ (1)

The sum of $\text{pH}$ and $\text{pOH}$ is equal to $14$ at $25{}^{°}\text{C}$.

$\text{pH}+\text{pOH}=14$ (2)

For a general reaction; $aA+bB\to cC+dD$

The equilibrium constant for this reaction can be written as follows,

$K_c=\frac{{\left[C\right]}^c{\left[D\right]}^d}{{\left[A\right]}^a{\left[B\right]}^b}$
