Predicting the Effect on Solubility of Adding Strong Acid
Problem: Write balanced equations to explain whether addition of H3O+ from a strong acid affects the solubility of:
(a) Iron (II) cyanide
(b) Potassium bromide
(c) Aluminum hydroxide
Plan: Write the balanced dissolution equation and note the anion. Anions of weak acids react with H3O+ and shift the equilibrium position toward more dissolution. Strong acid anions do not react, so added acid has no effect.
