If someone can help me with the steps involved in solving this problem, I would really appreciate it!
The Ksp value for Fe(OH)3 is 6.3 × 10-38
a. Calculate the solubility of Fe3+ at a pH of 8.00, assuming that it is controlled by the hydroxide. Express the concentration in both mmol/L and ppm.
b. Calculate the pH value at which the solubility of Fe3+ will be 100ppm.
c. Explain, in terms of Le Chatelier's principle, how raising or lowering the pH affects the solubility of Fe3+
