# Question #1ddc1

Formula for Potassium Sulphate is ${K}_{2} S {O}_{4}$ and the formula for Calcium Acetate is $C a {\left({C}_{2} {H}_{3} {O}_{2}\right)}_{2}$
Calcium has a charge of +2 and the Acetate (${C}_{2} {H}_{3} {O}_{2}$) has a charge of -1 so therefore the acetate is put in brackets and gets a subscript 2 behind it.
