The hydroxide ion has the formula OH^-. The solubility-productconstants for three generic hydroxides are given here. Generichydroxide
K_ 2.90 * 10^{-8}
Y(OH)_2 4.10 * 10^{-10} Z
(OH)_3 5.60 * 10^{-15}
The removal of an ion is sometimes considered to be complete whenits concentration drops to 1.00\times 10^{-6}~ M. Whatconcentration of hydroxide would cause Y^{2+} to "completely"precipitate from a solution?
At a pH of 10.5, arrange the solutions containing the followinggeneric hydroxides in order of decreasing concentration of thecation remaining in the solution (i.e., in order of increasingcompleteness of precipitation).
Rank from highest to lowest cation concentration. To rank items asequivalent, overlap them.
Y(OH)2, Z(OH)3, X(OH)
Is it Z(OH)3, Y(OH)2, X(OH)
