Dr.Bob you had told me to ignore 2x so I wondering if I wrote my did these steps correctly.
Calculate the molar solubility of nickel (II) hydroxide in 0.100 M sodium hydroxide
The solubility product of nickel (II) hydroxide at 25°C is 1.6 x 10-16.
Ni(OH)2 <=> Ni2+ + 2OH–
0.10/Ksp= 0.10/1.6 E-16
= 6.25 E14 > 500
Ksp = [Ni2+][OH-]2 = 1.6 x 10-16
