We have made atomic absorption measurements leading to the solubility of zinc hydroxide at 12.5, 25.0, 50.0, and 75.0 °C from pH = 6.7 to pH = 13.8. Results have been used for evaluation of the solubility product and stepwise constants for association of Zn 2+ (aq) with OH − (aq) to form solute species of type Zn(OH) i 2−i (aq) with i = 1–4. Evidence is presented to support the reliability of the various equilibrium constants. Uncertainties in derived enthalpies are assessed.
