Which of the following is least soluble?

Options

  1. AN i S ( K s p = 3 × 1 0 - 21 )
  2. BF e S ( K s p = 4 × 1 0 - 19 )
  3. CM n S ( K s p = 7 × 1 0 - 16 )
  4. DP t S ( K s p = 8 × 1 0 - 73 )

Correct answer

D. P t S ( K s p = 8 × 1 0 - 73 )

Step-by-step solution

Solubility depends on the solubility product greater the solubility and greater the solubility product. So P t S ( K s p = 8 × 1 0 - 73 ) is least soluble here and solubility order is MnS > FeS > NiS > PtS
