Solubility and Ksp

A 2.0 x 10^-3 solution of manganese (II) sulfate is gradually made more basic by the addition of 1.0 sodium hydroxide solution. At what pH will manganese (II) hydroxide begin to precipitate? (Ksp= 2 x 10^-13)
What is the balanced equation and how do you set the problem up?

What is the balanced equation and how do you set the problem up?

The reaction is:
MnSO4 (aq) + 2 NaOH (aq) Mn(OH)2 (s) + Na2SO4 (aq)
Eliminating any spectator ions gives:
Mn+2 (aq) + 2 ...
