Calculate the concentration of Ca²⁺ in a saturated solution of CaSO₄ that contains 0.1 M CaCl₂. K_sp= 2.5*10^-5 for CaSO₄.

Expert Solution

CaCl2(aq) ----------------> Ca^2+ (aq) + 2Cl^- (aq)

0.1M ------------------------ 0.1M

CaSO4(s) ---------------> Ca^2+ (aq) + SO4^2- (aq)

------------------------------- x +0.1------------ x

Ksp = [Ca^2+][SO4^2-]

2.5*10^-5 = (x+0.1)(x)

2.5*10^-5 = (0.1)(x) [ x + 0.1 = 0.1, x<<<<<0.1]

x = 2.5*10^-4

The concentration of Ca^2+ = x + 0.1

= 2.5*10^-4 + 0.1

= 0.10025M >>>>answer
