Write the Ksp expression for the sparingly soluble compound chromium(III) hydroxide, Cr(OH)3. Ksp =

Answer and Explanation: Ksp is the Solubility Product Constant and is the equilibrium constant that happens when a solid is dissolved in an aqueous solution.

The dissolution of chromium (III) hydroxide:

⇄

Every equilibrium constant is of the form:

Then,

The reagent is not included because solids don't take part in euqilibrium constants.

So, Ksp of chromium (III) hydroxide is
