Answer:

B.
Na_2SO_4

Step-by-step explanation:

Hello,

The solubility of HgS is increased by adding
Na_2SO_4 due to common ion effect which consists on the effect that the higher solubility of
has over the HgS as the sulfur-based ions modify the solubility product. In such a way, by adding the sulfate, the equilibrium will be shifted rightwards, therefore the solubility is increased.

Best regards.
