Question

A saturated solution of manganese(II) hydroxide was prepared, and an acid-base titration was performed to determine its Ksp at 25 degrees C. The endpoint was reached when 40.00 mL of the manganese(II) hydroxide solution was titrated with 3.34 mL of 0.0020 M HCl solution. What is the Ksp of manganese(II) hydroxide?

M1 = (M2V2/n2) × ( n1/V1)

M1 = (0.002 M × 3.34 mL / 2 mol ) × ( 1 mol / 40.00 mL)

M1 = 0.0000835 M

Ksp = 4S^3

Ksp = 4×(0.0000835)^3

Ksp = 2.3 ×10^-12
