Answer to Problem 102A

Formula of the sodium sulfate is Na2SO4.

Explanation of Solution

The sulfate anion is a polyatomic anion and carries a −2 charge and the formula is SO42−. Sodium is group 1 element and carries +1 charge. Therefore, two ions combine with SO42− to produce Na2SO4.

(d)

Interpretation Introduction

Interpretation:
