The hydroxide ion has the formula OH-. The solubility-product constants for three generic hydroxides are given here. XOH = 2.90 x 10-8 Ksp Y(OH)2 = 2.20 x 10-10 Ksp Z(OH)3 = 8.20 x 10-15 Ksp The removal of an ion is sometimes considered to be complete when its concentration drops to 1.00 x 10-6 M. What concentration of hydroxide would cause Y+2 to "completely" precipitate from a solution?
The hydroxide ion has the formula OH−. The solubility-product constants for three generic hydroxides are given here. Generic hydroxide Ksp XOH 2.70×10−8 Y(OH)2 2.60×10−10 Z(OH)3 7.00×10−15 The removal of an ion is sometimes considered to be complete when its concentration drops to 1.00×10−6 M. What concentration of hydroxide would cause Y2+ to "completely" precipitate from a solution?
What is the hydroxide ion concentration, [OH-], in a solution with a hydronium ion concentration, [H3O+] = (1.42x10^-3) M? NOTE: The problem statement uses the caret symbol, "^" to indicate exponentiation and shows the entire value in parentheses. For example: The value 1.37 x 10-4 would be shown as (1.37x10^-4). Note: Your answer is assumed to be reduced to the highest power possible.
