Question

`"K"_"sp"` for HgSO₄ is `6.4 xx 10^-5`, what is the solubility of the salt?

विकल्प

• `8 xx 10^-3`

• `8 xx 10^-2`

• `8 xx 10^-4`

• `8 xx 10^-5`

Answer 1

`bb(8 xx 10^-3)`

Explanation:

Let the solubility of the salt be

S = `sqrt("K"_"sp")`   ...(where, K_sp = solubility product)

`= sqrt(6.4 xx 10^-5) = 8 xx 10^-3 "mol L"^-1`
