The best explanation for the solubility ...

The best explanation for the solubility of MnS in dil. HCI is that:

A

solubility product of `MnCI_(2)` is less than that of MnS

B

concentration of `Mn^(2+)` 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 `H_(2)S`

Text Solution

Verified by Experts

The correct Answer is:
D
`MnS+2HCIrarrMnCI_(2)+H_(2)S`, The dissociation of `H_(2)S` (formes) is suppressed due to the presence of HCI.
