Question

plzzz tell me asnwer ​

Answer 1

A2X3 is dissociated:

A2X3 = 2A^3+ +3X^2-

let the solubility of A2X3 be S

ksp=(A^3+)^2 ×(B^2-)^3

1.1×10^-23=(2S)^2×(3S)^3

1.1×10^-23=108 S^5

S^5 = 1.1×10^-23 / 108

S^5 = 1×10^-25 .... (approx.)

S= (1×10^-25)^1/5

S=1×10^-5

Hence,the solubilty of A2X3 is 1×10^-5 molL^-1
