The best explanation for the solubility of MnSin dil. HCl is that

Answer»

Solubility PRODUCT of `MnCl_(2)` is less than that of MnS
CONCENTRATION of `Mn^(2+)` is LOWERED by the formation of complex ions with CHLORIDE ions
Concentration of sulphide ions is lowered by oxidation to free sulphur
Concentration of sulphide ions is lowered by formation of the weak acid `H_(2)S`

SOLUTION :It is a characteristic property of IV group, concentration of sulphide ions is lowered by formation of the weak acid `H_(2)S` .
