MHT CET Chemistry question
The concentration of sulphide ion in 0.1 M HCl solution saturated with hydrogen sulphide is M. If 10 mL of this is added to 5 mL of 0.04 M solution of the following: , , and , in which of these solutions precipitation will take place? (Given, of FeS = , of MnS = , of ZnS = , of CdS = )
Answer: (B)
Solution
After mixing (15 mL) M and M, so the ionic product is ; this exceeds of
