Chapter 3.3, Problem 3.3PSP

(a)

Interpretation Introduction

Interpretation:

The balanced equation for the dissociation of given ${{\text{(NH}}_{\text{4}}\text{)}}_{\text{2}}\text{S}$ ionic compound in water has to be written.

Concept introduction:

Balancing reaction:

Balanced reaction is a chemical reaction in which number of atoms for each element in the reaction and the total charge are same on both reactant side and the product side.

Steps in balancing the information

• Step 1: Write the unbalanced equation
• Step 2: Find the coefficient to balance the equation.
• The coefficient should be reduced to the smallest whole number.

Dissociation:

When ionic compound dissolved in water it produced cation and anion, this process is called as dissociation.
