if the solubilty of AgC2H3O2 is 5.0 x10^-2mol/L. What is the Ksp?

Answer 1

Call AgC2H3O2 as AgAc.

.........AgAc ==> Ag^+ + Ac^-
I.......solid.....0.......0
C.......solid.....x.......x
E.......solid.....x.......x

Ksp = (Ag^+)(Ac^-+
Ksp = (x)(x)
You are given the value of x, substitute that value and solve for Ksp.
