Question
a) What is the solubility of copper(II) iodate, Cu(IO;)2?
Ksp. = 1.4 x 107 at 25 °C
%3D
b) Will the solubility of Cu(IO3)2 (s) increase, decrease or remain the same if some solid
Cu(NO:)2 is added? (copper(II) nitrate is very soluble and completely dissolves)
c) Aqueous copper(II) ions, Cu²*
to the reaction:
(a0), react with aqueous ammonia to form a complex according
Cu2+,
(a0+ 4NH3 (a) [Cu(NH3)4]* (aq) with a formation constant, Ke= 1.2 x 1013
How will the addition of aqueous NH3 effect the solubility of Cu(IO3)2 (s)?
(increase, decrease or no effect)
