Q5. pH and Solubility (Easy)
Suppose you are provided with aqueous Zn(OH)2 with
the Ksp value to be 4.5 x 10-17. Determine the solubility
of Zn2+ ion in pure water and the resulting pH of the
solution at equilibrium
Calculate the solubility of Zn2+ ion when the Zn(OH)2 is
dissolved into a solution buffered at pH=6.0. Explain in
terms of Le Chatelier’s principle
