Homework Statement
Zinc hydroxide has the chemical formula of Zn(OH)2. It has a very low solubility. What is the solubility in g/L of Zinc Hydroxide in a solution with a pH of 8?
Homework Equations
zinc hydroxide formula
14-pH = pOH[/B]
The Attempt at a Solution
10^-6 (the pOH) gives me the concentration of the OH- ion.
That gives me the unknown in mols/L.
I multiply it by the molar mass, but it's wrong. What am I doing wrong?
