Question

Which of the following metal sulphide has maximum solubility in water? (A) CdS( K sp =36 × 10-30) (B) FeS( K sp =11 × 10-20) (C) HgS( K sp =32 × 10-54) (D) ZnS ( K sp =11 × 10-22)

The salt with highest Ks p is most soluble. Thus; FeS will be most soluble.

Q. Which of the following metal sulphide has maximum solubility in water?

$C d S (K_{s p} = 36 \times 1 0^{- 30})$

$F e S (K_{s p} = 11 \times 1 0^{- 20})$

$H g S (K_{s p} = 32 \times 1 0^{- 54})$

$Z n S (K_{s p} = 11 \times 1 0^{- 22})$

The salt with highest $K_{s p}$ is most soluble. Thus; $F e S$ will be most soluble.

Q. Which of the following metal sulphide has maximum solubility in water?

CdS(Ksp​=36×10−30)

FeS(Ksp​=11×10−20)

HgS(Ksp​=32×10−54)

ZnS(Ksp​=11×10−22)

The salt with highest Ksp​ is most soluble. Thus; FeS will be most soluble.

$C d S (K_{s p} = 36 \times 1 0^{- 30})$

$F e S (K_{s p} = 11 \times 1 0^{- 20})$

$H g S (K_{s p} = 32 \times 1 0^{- 54})$

$Z n S (K_{s p} = 11 \times 1 0^{- 22})$

The salt with highest $K_{s p}$ is most soluble. Thus; $F e S$ will be most soluble.
