Chapter 8, Problem 10A

Interpretation Introduction

Interpretation: Whether a precipitate is formed or not is to be determined when sodium sulphate is mixed with calcium chloride.

Concept Introduction: During double displacement reaction certain ionic solutions produce undissolved solid residue called precipitate.

The formation of precipitate can be determined by using solubility rules.

Answer to Problem 10A

Calcium sulphate precipitate is formed.

Explanation of Solution

When sodium sulphate aqueous solution is mixed with calcium chloride, then calcium sulphate precipitate is formed.
