A) Only \[ZnS\] precipitates
B) Both \[CuS\] and \[ZnS\] precipitate
C) Only \[CuS\] precipitates
D) No precipitation occurs
Correct Answer: B
Solution :
The ionic product for \[ZnS\,(0.1\times 8.1\times {{10}^{-19}})\]and for \[CuS\,(0.01\times 8.1\times {{10}^{-19}})\] exceeds their \[{{K}_{sp}}\] values. Hence, both get precipitated.You need to login to perform this action.
