The solubility of the salt `M_(m) A_(n)` in water is `'s'` moles per litre. The solubility product of the salt is (at constant temperature)

Options

A. `M^(m) A^(n)`
B. `(m+n)S^(m+n)`
C. `m^(m)n^(n)s^(m+n)`
D. `M^(m)A^(n)s`

Answer

C

Explanation

`M_(m)A_(n) hArr underset(ms)(mM)^(+n) + underset(ns)(nA)^(-m)`
`M_(m)A_(n) hArr underset(ms)(mM)^(+n) + underset(ns)(nA)^(-m)`
`k_(sp) = (ms)^(m) (ns)^(n)`
`= m^(m).n^(n).s^(m+n)`
