Chapter 22, Problem 22.78P

Interpretation Introduction

Interpretation:

The pH at which one can separate copper ion and nickel ion has to be calculated.

Concept Introduction:

• pH is the negative logarithm of hydronium ion concentration.  It is given as,

      $\text{pH}\text{=}{\text{-log}}_{\text{10}}{\text{(H}}_{\text{3}}{\text{O}}^{\text{+}}\text{)}$

• ${\text{pK}}_{\text{a}}$ is the negative logarithm of acid dissociation constant.  It is given as,

        ${\text{pK}}_{\text{a}}\text{=}{\text{-log}}_{\text{10}}{\text{K}}_{\text{a}}$
