A) Only NS gets precipitated
B) Only MS gets precipitated
C) No sulphide precipitates
D) Both sulphides precipitate
Correct Answer: D
Solution :
The concentration of \[{{S}^{2-}}\]ions in group II is lowered by maintaining acidic medium in the presence of \[N{{H}_{4}}Cl\]. The ionization of \[{{H}_{2}}S\] is supressed due to common ion effect. So the ionic product is less than solubility product.You need to login to perform this action.
