Solution

The correct option is C $A l_{2} (S O_{4})_{3}$
Higher is the charge, higher is the coagulating power.

$S b_{2} S_{3}$ sol is negatively charged sol. It will be coagulated by positively charged ions.

In $A l_{2} (S O_{4})_{3}$ , $A l^{3 +}$ ion has maximum charge among the given electrolytes.

Among the electrolytes $N a_{2} S O_{4}, C a C l_{2}, A l_{2} (S O_{4})_{3}$ and $N H_{4} C l$ , the most effective coagulating agent for $S b_{2} S_{3}$ sol is $A l_{2} (S O_{4})_{3}$ .

Hence, option $C$ is correct.
