Answer #1

0.10 M Mn(CH3COO)2 -------------- Less soluble than in pure water.

0.10 M (NH4)2S   -------------           Less soluble than in pure water.

0.10 M NaNO3    -------------------         Similar solubility as in pure water.

0.10 M NH4CH3COO ------------- Similar solubility as in pure water.

Explanation :

MnS   ------------> Mn2+   +   S2-

Mn(CH3COO)2 and (NH4)2S have common ions. so solubility is less than in pure water .

NaNO3 and NH4CH3COO have similar solubility as in pure water. because these are neutral medium.
