If the solubility of copper(II) iodate Cu(IO3)2 is reported as 0.12 g per 100 mL, what is the solubility product constant for this salt?
A. 9.8 × 10-8
B. 8.6 × 10-7
C. 7.3 × 10-6
D. 6.4 × 10-5
What is the minimum pH at which cobalt(II) hydroxide [Ksp = 2.0 × 10^-16] will precipitate from a solution 0.020 M in Co2+?
The molar mass of Cu(IO3)2 = Cu (63.6) + 2 I (2 x 126.9) + 6 O (6 x 16.0) = 413.4 g/mole.
Moles of copper iodate can be calculated as
Cu(IO3)2 dissolves to give 1 mole of Cu2+ and 2 moles of IO3-.
So, moles Cu2+ = 2.90 x 10-4 moles and moles IO3- = 5.80 x 10-4 moles IO3-
Molarity = moles/L
The solubility product ca...
