Question

Verified Solution • 2025–26 Session moderate

A₃B₂ is a sparingly soluble salt of molar mass M (g mol^{$-$ 1}) and solubility x g L^{$-$ 1}. The solubility product satisfies

{K_{sp}} = a{\left( {{x \over M}} \right)^5}

. The value of a is _____________. (Integer answer)

Accepted Answer

K_SP = (3s)³ (2s)²

K_SP = 108 s⁵ & s = (x/M)

K_SP = 108

{\left( {{x \over M}} \right)^5}

given

{K_{sp}} = a{\left( {{x \over M}} \right)^5}

comparing a = 108
