Ferric hydroxide, Fe(OH) 3 , is an insoluble salt with a so lubility product of 10 ^-39 . What is the maximum concentration of ferric hydroxide that can dissolve? Using Le Chatalier's Principle, explain why iron (III) solutions are more soluble in acidic solution.

Answer:

7.80x10^-11 M

Fe(OH)_3(s) <--> Fe³⁺_(aq) + 3OH-_(aq)

The acid reacts with OH-, according to the following equation:

H⁺ + OH^- --> H₂O

As a result, the concentration of OH- is reduced. According to Le Chatelier's principle, if the concentration of the product decreases, the equilibrium will shift to the right to compensate for the product lost. Therefore, the equilibrium will favor the dissolution of Fe(OH)₃. It becomes more soluble.
