Question

The best explanation for the solubility of MnS in dil. HCl in salt 

(A) Solubility product of MnCl₂ is less than that of MnS 

(B) Concentration of Mn²⁺ is lowered by the formation of complex ions with chloride ions. 

(C) Concentration of sulphide ions is lowered by oxidation to free sulphur. 

(D) Concentration of sulphide ions is lowered by formation of the weak acid H₂S 

Answer 1

Correct Option (D) Concentration of sulphide ions is lowered by formation of the weak acid H₂S

Explanation:

 Conc. of S^2– ion is covered by formation of weak acid H₂S.
