Question

If Ks p is the solubility products of a sparingly soluble salt A3 X2, then its solubility is : (A) (Ks p / 108)1 / 5 (B) (Ks p)1 / 5 (C) (K text sp / 72)1 / 5 (D) (Ks p)1 / 2

underset 1-sA3 X2 leftharpoons underset 3s3A2+ + underset 2s2X3- K mathrmsp=(3 s)3(2 s)2=108 s5 s=((Ks p/108))1 / 5

Q. If $K_{s p}$ is the solubility products of a sparingly soluble salt $A_{3} X_{2}$ , then its solubility is :

$(K_{s p} /108)^{1/5}$

$(K_{s p})^{1/5}$

$(K_{sp} /72)^{1/5}$

$(K_{s p})^{1/2}$

$1 - s A_{3} X_{2} ⇌ 3 s 3 A^{2 +} + 2 s 2 X^{3 -}$

$K_{sp} = (3 s)^{3} (2 s)^{2} = 108 s^{5}$

$s = (\frac{K _{s p}}{108})^{1/5}$

Q. If Ksp​ is the solubility products of a sparingly soluble salt A3​X2​, then its solubility is :

(Ksp​/108)1/5

(Ksp​)1/5

(Ksp ​/72)1/5

(Ksp​)1/2
