Strontium sulfate becomes less soluble in an aqueous solution when sodium sulfator is added because O the addition of sulfate ions shifts equilibrium to the left.
O the addition of sodium ions shifts equilibrium to the left.
O the addition of sulfate ions shifts equilibrium to the right. Chd
O the addition of sodium ions shifts equilibrium to the right.​

The addition of sulfate ions shifts equilibrium to the left.

Explanation:

Hello!

In this case, according to the following ionization of strontium sulfate:

It is evidenced that when sodium sulfate is added, sulfate, is actually added in to the solution, which causes the equilibrium to shift leftwards according to the Le Ch athelier's principle. Thus, the answer in this case would be:

The addition of sulfate ions shifts equilibrium to the left.
