Question
The best explanation for the solubility of MnS in dilute HCl is that :
Options
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 weak acid H2S
Solution
MnS(s) ⇋ Mn2+ (aq) + S2- (aq) ;
S2- (aq) + 2H+ (aq) H2S (aq)
S2- (aq) + 2H+ (aq) H2S (aq)
