Solid MX dissolves in water but only limited amount.
MX(s) <-> M+(aq) + X- (aq)
The solubility of MX in a solution buffered to pH=2.00 is only 3.17 x 10^-8M. It turns out that HX is a weak acid. (Ka= 1.00 x 10^-15M)
(a) Given that, would you expect the solubility of MX in pure water to be bigger or smaller than that is in 2.00 pH buffer? Why?
(b) Calculate the Ksp for MX.
