Calculation of when a compound precipitates given pH of a solution.?

An aqueous solution of Ni(NO3)2 is slowly added to a beaker of water with a pH of 9.85. At what concentration of Ni(NO3)2 will Ni(OH)2start to precipitate? Ksp for nickel(II) hydroxide is 1.60 x 10-14. 4.21 x 10-6 M 3.63 x 10-6 M 3.05 x 10-6 M 3.19 x 10-6 M 3.73 x 10-6 M 2.92 x 10-6 M 4.24 x 10-6 M show more An aqueous solution of Ni(NO3)2 is slowly added to a beaker of water with a pH of 9.85.
