The solubility of Fe+3ions will increases, when the concentration ofhydroxide ion decreases then hydrogen ions will increase and pH of solution will be decreased.

Dear student 
Ksp (Fe(OH)3) is 2.8 × 10^–39 at 25 °C. From the chemical equation, Ksp = [Fe3+(aq)][OH-(aq)]^3. Before the Industrial Revolution, the concentration of OH–(aq) in the oceans was about 1.6 × 10^–6 M
