Calculate the solubility of C6H5COOAg(s) in a buffer solution that has a pH of 3.20. (Ka = 6,5 x10^-5M ; Ksp = 2,5 x10^-5M^2)
Henderson-Hasselbach, Ksp equation
The Attempt at a Solution
This is driving me nuts. I used Henderson-Hasselbach to find [C6H5COO], wrong answer, tried an equilibrium problem, wrong answer. Can someone give me a method for this. Thanks.
