Answer:
The addition of sulfate ions shifts equilibrium to the left.
Explanation:
Hello!
In this case, according to the following ionization of strontium sulfate:
[tex]SrSO_3(s)\rightleftharpoons Sr^{2+}+SO_4^{2-}[/tex]
It is evidenced that when sodium sulfate is added, sulfate, [tex]SO_4^{2+}[/tex] 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.
Best regards!
