Chapter 4, Problem 9SAQ

Interpretation Introduction

Interpretation:

The solution that forms a precipitate when mixed with a solution of aqueous ${\text{Na}}_{\text{2}}{\text{CO}}_{\text{3}}$ is to be identified.

Concept Introduction: According to solubility rules, all compounds that are alkali metals are soluble in water, the compounds containing ammonium salts are also soluble. Most of the sulfides that are present in the transition metals are highly insoluble.

To increase the stability of the solution, precipitation lowers the solute concentration to the saturation.

To determine: The solution that forms a precipitate when mixed with a solution of aqueous ${\text{Na}}_{\text{2}}{\text{CO}}_{\text{3}}$ .
Correct answer: The ${\text{CuCl}}_{\text{2}}$ solution forms a precipitate when mixed with a solution of aqueous ${\text{Na}}_{\text{2}}{\text{CO}}_{\text{3}}$ . Therefore, the correct option is (d).
