A saturated solution of an unknown metal (III) hydroxide was filtered to remove

Question

A saturated solution of an unknown metal (III) hydroxide was filtered to remove any excess solids. Then a 16.00 mL sample of the saturated solution was titrated to the end point with a 0.12 M solution of HCl.

If it took 12.20 mL of HCl to titrate to the endpoint,

a) What is the molar concentration of hydroxide ion in the saturated solution?

M

b) What is the molar concentration of the unknown metal (III) cation in the saturated solution?

M

c) What is the Ksp for this unknown metal (III) hydroxide?

Explanation / Answer

a) Molar concentration of hydroxide ion is 0.0305 mol/L

b) Molar concentration of the unknown metal (III) cation is0.0101 mol/L

c) Ksp for this unknown metal (III) hydroxide is 9.45 x 10-6
