Chapter 18, Problem 18.109CHP

Interpretation Introduction

Interpretation: The balanced equation for the exchange of sulfate by chloride should be written.

Concept introduction:

In a balanced equation the number of atoms of each element as a reactant is equal to the number of atoms of that element as a product.

Coefficient is a number placed before a formula in a chemical equation.

A balanced equation should be obeying the law of conservation of mass. Law of conservation of mass states that, the number of atoms remains constant throughout the reaction, simply it can be stated as follows, “during a chemical reaction atoms are neither be created nor be destroyed”.

Ion exchange one of the important processes used to remove the hardness of water. In this process an exchange of ions between two electrolytes or between an electrolyte solution and a complex would be occurs.
