The solution containing Mn^(2+), Fe^(2+), Zn^(2+) and Hg^(2+) concentration is 10^(-3) M. If K_(sp) of Mns, FeS, ZnS an HgS are respectively 10^(-15), 10^(-2), 10^(-4), 10^(-54) than which one is the first precipitate by H_2S ?

The solution containing Mn^(2+), Fe^(2+), Zn^(2+) and Hg^(2+) concentr

1.	The solution containing Mn^(2+), Fe^(2+), Zn^(2+) and Hg^(2+) concentration is 10^(-3) M. If K_(sp) of Mns, FeS, ZnS an HgS are respectively 10^(-15), 10^(-2), 10^(-4), 10^(-54) than which one is the first precipitate by H_2S ?
Answer» FeS HgS MnS ZnS Solution :`K_(SP)` is LEAST , PRECIPITATION will be FAST.
