Chapter 9.5, Problem 13PPC

Interpretation Introduction

Interpretation:

The correct representations for the mixture of ${\text{NaCl and BaCl}}_{\text{2}}$ solution should be given from given representations.

Concept introduction:

Concentration of ion:

The electrolyte is chemical compound, which dissociates to produce the ions in aqueous solutions.

The concentrations of produced ions in aqueous solution are given by the multiplication of coefficient of the ion with concentration of solution.

The electrolytic solutions maintain the electrical neutrality by charge and number of ions.

$\text{Ionic concentrations}\text{=}\text{solution}\text{concentration}\times \text{Ionic}\text{coefficients}$
