Chapter 8, Problem 10A

(a)

Interpretation Introduction

Interpretation: The solubility of lead (II) chloride according to the solubility rules needs to be explained.

Concept Introduction: Solubility can be defined as the amount of compound in the solvent. It is represented as g/mL or g/L of the solvent.

There are certain solubility rules purposed to explain the solubility of compounds in water as solvent. A less soluble compound tends to form precipitate at the bottom during dissolution.

Answer to Problem 10A

Lead (II) chloride is insoluble salt.

Explanation of Solution

According to the solubility rule; Salts containing Cl -, Br -, or I -  ; halide ions are soluble with exceptions as Ag+, Pb2+, and (Hg2)2+ . Thus PbCl2 or lead (II) chloride is insoluble in water as it contains Pb2+ ions and Cl - ions.

(b)

Interpretation Introduction

Interpretation: The solubility of barium sulfate needs to be explained according to the solubility rules.

Concept Introduction: Solubility can be defined as the amount of compound in the solvent. It is represented as g/mL or g/L of the solvent.

There are certain solubility rules purposed to explain the solubility of compounds in water as solvent. A less soluble compound tends to form precipitate at the bottom during dissolution.

Answer to Problem 10A

Barium sulphate is insoluble salt.

Explanation of Solution

According to the solubility rule; almost all sulphates are soluble in water with exceptions as  CaSO4, BaSO4, PbSO4, Ag2SO4 and SrSO4 . Thus, BaSO4 or barium sulphate is insoluble in water as it contains Ba2+ and SO4 -2 ions.

(c)

Interpretation Introduction

Interpretation: The solubility of iron (II) sulfide needs to be explained according to the solubility rules.

Concept Introduction: Solubility can be defined as the amount of compound in the solvent. It is represented as g/mL or g/L of the solvent.

There are certain solubility rules purposed to explain the solubility of compounds in water as solvent. A less soluble compound tends to form precipitate at the bottom during dissolution.

Answer to Problem 10A

Iron (II) sulfide is insoluble salt.

Explanation of Solution

According to the solubility rule; most of the sulfide of transition metals are insoluble in water.

Here the given sulfide is iron (II) sulfide. Iron is a transition metal as it is placed in the 3d-series of the d-block element. Thus iron (II) sulfide is insoluble in water.

(d)

Interpretation Introduction

Interpretation: The solubility of Aluminium hydroxide needs to be explained according to the solubility rules.

Concept Introduction: Solubility can be defined as the amount of compound in the solvent. It is represented as g/mL or g/L of the solvent.

There are certain solubility rules purposed to explain the solubility of compounds in water as solvent. A less soluble compound tends to form precipitate at the bottom during dissolution.

Answer to Problem 10A

Aluminium hydroxide is insoluble salt.

Explanation of Solution

According to the solubility rule; hydroxide salts are slightly soluble and there are many hydroxides which are insoluble in water. The hydroxide of alkali metals are soluble in water whereas hydroxides of alkaline earth metal are slightly soluble in water.

On the contrary, hydroxides of transition metals and aluminium are insoluble in water. Thus Aluminium hydroxide is insoluble in water.
