Question

Which of the following is least soluble? (A) NiS(.Ks p=3× 10- 21.) (B) FeS(.Ks p=4× 10- 19.) (C) MnS(.Ks p=7× 10- 16.) (D) PtS(.Ks p=8× 10- 73.)

Solubility depends on the solubility product greater the solubility and greater the solubility product. So PtS(.Ks p=8× 10- 73.) is least soluble here and solubility order is MnS > FeS > NiS > PtS

Q. Which of the following is least soluble?

$N i S (K_{s p} = 3 \times 1 0^{- 21})$

$F e S (K_{s p} = 4 \times 1 0^{- 19})$

$M n S (K_{s p} = 7 \times 1 0^{- 16})$

$PtS (K_{s p} = 8 \times 1 0^{- 73})$

Solubility depends on the solubility product greater the solubility and greater the solubility product.

So $PtS (K_{s p} = 8 \times 1 0^{- 73})$ is least soluble here and solubility order is

MnS > FeS > NiS > PtS

Q. Which of the following is least soluble?

NiS(Ksp​=3×10−21)

FeS(Ksp​=4×10−19)

MnS(Ksp​=7×10−16)

PtS(Ksp​=8×10−73)

Solubility depends on the solubility product greater the solubility and greater the solubility product. So PtS(Ksp​=8×10−73) is least soluble here and solubility order is MnS > FeS > NiS > PtS

$N i S (K_{s p} = 3 \times 1 0^{- 21})$

$F e S (K_{s p} = 4 \times 1 0^{- 19})$

$M n S (K_{s p} = 7 \times 1 0^{- 16})$

$PtS (K_{s p} = 8 \times 1 0^{- 73})$

Solubility depends on the solubility product greater the solubility and greater the solubility product.

So $PtS (K_{s p} = 8 \times 1 0^{- 73})$ is least soluble here and solubility order is

MnS > FeS > NiS > PtS
