Answer #1

The solubility product K5=[Y2+1x [OH-] = 1.90 x 10-10 ... ...(1)

Y^{2+ } will completely precipitate from solution when Y2+1 = 1.00 x 10-6 M

Substitute this in equation (1)

Ksp = [Y2+] x [OH)2 = 1.90 x 10-10 1.00 x 10-6 x [OH-12 = 1.90 x 10-10 JOH-12 [OH^2 = 1.00 x 10-6 1.90 x 10-10 [OH-] = 1.90 x
