Chapter 10.15, Problem 2QQ

Interpretation Introduction

Interpretation:

A molar amount of an ion that is not equal to one equivalent of ion ions has to be identified from the given options.

Concept-Introduction:

Body fluids have small amounts of different type electrolytes and its concentration is measured in equivalents or milliequivalents per liter. An Equivalent $\left(Eq\right)$ of an ion is the molar amount of a certain ion required for supplying one mole of negative or positive charge.

Few examples for the relationship between number of equivalent and charge of an ion is given below,

  $\begin{array}{l}1\text{ mole = 1 equivalent}\left(\text{For ions with charge 1+ or 1}-\right)\\ \\ 1\text{ mole = 2 equivalent}\left(\text{For ions with charge 2+ or 2}-\right)\\ \\ 1\text{ mole = 3 equivalent}\left(\text{For ions with charge 3+ or 3}-\right)\end{array}$
