Chapter 26.1, Problem 1TY

Interpretation Introduction

Interpretation:

The milli equivalents of ${\text{H}}^{\text{+}}$ that will replaced by $\text{100 mL of 26}{\text{.3 mM Ni}}^{\text{2+}}$ in cation exchange column should be calculated.

Concept introduction:

Equivalents in ion-exchange column:

In the separation of cations in cations exchange column, the equivalent is calculated by the amount of cations that will exchanged by one mole of a monovalent cation such as ${\text{H}}^{\text{+}}$

${\text{nR}}^{\text{-}}{\text{H}}^{\text{+}}{\text{+M}}^{\text{n+}}\stackrel{}{\to }{\text{R}}_{\text{n}}^{\text{-}}{\text{M}}^{\text{n+}}{\text{+}}_{\text{n}}{\text{H}}^{\text{+}}$

From the above equation the equivalent is,

$\text{eq}\text{=}\text{n×(moles}\text{of}{\text{M}}^{\text{n+}}\text{)}$.
