(a) Interpretation: The reason for Al (OH) 3 (s) to be soluble in NaOH (aq) but not in NH 3 (aq) needs to be explained. Concept introduction: Lewis acid and Lewis base reacts to form coordination complex in which central metal atom is surrounded by neutral molecules or anions through covalent bonds. In fact, ligands are Lewis bases because they can donate electrons and metal atoms are Lewis acid with vacant d orbital as they can accept elecetrons.

(b)

Interpretation:

The reason for ZnCO₃ (s) to be soluble in NH₃ but ZnS (s) to be insoluble in NH₃ needs to be explained.

Concept introduction:

Coordination complex is consisting of a central atom that is surrounded by molecules or ions called ligands. These are formed when Lewis acid and Lewis base reacts with each other.

Interpretation Introduction

(c)

Interpretation:

The reason for the molar solubility of AgCl in pure water to be 1 ×10−5M, in 0.4 M NaCl to be 2 ×10−5M and in 1M NaCl to be 8×10−5M needs to be explained.

Concept introduction:

Ionic compounds are soluble depending on the product of concentrations of the ions they form after dissociation. If the ions are already present in the solution, then the solubility is affected by the presence of either of the ions. By altering the presence of ions in the solution, it is possible to manipulate the solubility of different compounds. This effect is the common ion effect.
