Question

determine the formula for each compound from its name. calcium sulfite:

Explanation:

Step1: Identify ion charges

Calcium ion ($Ca^{2 +}$) has a +2 charge, sulfite ion ($SO_{3}^{2 -}$) has a - 2 charge.

Step2: Balance charges

Since the magnitudes of the charges of calcium and sulfite ions are equal, the ratio of ions in the compound is 1:1.

Answer:

$CaSO_{3}$
