The balanced molecular, total ionic, and net ionic equations for the reaction that occurs when the solutions are mixed are to be determined. Concept introduction: There are three types of equations that are utilized to represent an ionic reaction: 1. Molecular equation 2. Total ionic equation 3. Net ionic equation The molecular equation represents the reactants and products of the ionic reaction in undissociated form. In total ionic reaction, all the dissociated ions that are present in the reaction mixture are represented and in net ionic reaction, the useful ions that participate in the reaction are represented. Precipitation reaction involves the reaction of two soluble ionic compounds to form an insoluble product. The insoluble product is known as a precipitate.

Question

Chapter 4, Problem 4.150P

(a)

Interpretation Introduction

Interpretation:

The balanced molecular, total ionic, and net ionic equations for the reaction that occurs when the solutions are mixed are to be determined.

Concept introduction:

There are three types of equations that are utilized to represent an ionic reaction:

1. Molecular equation

2. Total ionic equation

3. Net ionic equation

The molecular equation represents the reactants and products of the ionic reaction in undissociated form. In total ionic reaction, all the dissociated ions that are present in the reaction mixture are represented and in net ionic reaction, the useful ions that participate in the reaction are represented.

Precipitation reaction involves the reaction of two soluble ionic compounds to form an insoluble product. The insoluble product is known as a precipitate.

(b)

Interpretation Introduction

Interpretation:

Mass of precipitate formed when the yield is 100 % is to be calculated.

Concept introduction:

Precipitation reaction involves the reaction of two soluble ionic compounds to form an insoluble product. The insoluble product is known as a precipitate.

The reason for the precipitation reaction to occur is the formation of a product that is insoluble in nature. The insoluble product is formed when the electrostatic attraction between the ions is greater as compared to the attraction between ions and water molecule. The product will remain intact and precipitate out from the solution.

(c)

Interpretation Introduction

Interpretation:

The concentration of each ion in solution after reaction is to be calculated.

Concept introduction:

Precipitation reaction involves the reaction of two soluble ionic compounds to form an insoluble product. The insoluble product is known as a precipitate.

The reason for the precipitation reaction to occur is the formation of a product that is insoluble in nature. The insoluble product is formed when the electrostatic attraction between the ions is greater as compared to the attraction between ions and water molecule.
