Given that, Ksp for HgSO4=6.4× 10-5 HgSO4 is a binary salt, hence, for it, Ksp=S2 ∴ S=√Ksp =√6.4× 10-5=8× 10-3 mol text/litre

Q. If $K_{s p}$ for $H g S O_{4}$ is $6.4 \times 10^{- 5},$ then solubility of its salt is:

$6.4 \times 10^{- 5} mol litr e^{- 1}$

$6.4 \times 10^{- 3} mol litr e^{- 1}$

$8 \times 10^{- 6} mol litr e^{- 1}$

$8 \times 10^{- 3} mol litr e^{- 1}$

Given that, $K_{s p}$ for $H g S O_{4} = 6.4 \times 10^{- 5}$ $H g S O_{4}$ is a binary salt, hence, for it, $K_{s p} = S^{2}$ $∴$ $S = K_{s p}$ $= 6.4 \times 10^{- 5} = 8 \times 10^{- 3} m o l / l i t re$
