7.73 The concentration of sulphide ion in 0.1M HCl solution saturated with hydrogen sulphide is 1.0 × 10-19 M. If 10 mL of this is added to 5 mL of 0.04 M solution of the following: in which of these solutions precipitation will take place?
the concentration of and the volume of the solution containing sulphur ion = 10 mL.
Volume of metal salts solution added = 5mL
Volume = 15 mL
So, the concentration of
So, the ionic product =
For the precipitation of the solution, the ionic product should be greater than the corresponding values.
of are and respectively.
Hence precipitation will take place in and metal salts.
