Problem- A saturated solution of manganese(II) hydroxide was prepared, and an acid-base titration was performed to determine Ksp at 25 degrees celcius. The endpoint was reached when 75.00mL of the managanese(II) hydroxide solution was titrated with 6.32mL of 0.0010M HCl solution. What is the Ksp of manganese (II) hydroxide?
Please show me how work it out above problem
