Chemistry-weak acid affects the pH?
posted by Amy on .
For which salt in each of the following groups will the solubility depend on pH?
please explain why its the answer
Look at how each ionizes in solution. For example, AgCl ==> Ag^+ + Cl^-
Now look at the products and see if H^+ (which is what you are changing when you change the pH), will react with either of the products. If it will, then the pH will affect the solubility. In this case, there is no reaction with either Ag ion or Cl ion; therefore, the pH will not affect the solubility of AgCl. Do the same kind of analysis on the other two.
