100.0mL of 0.400 mol/L CoCl2 (aqueous) is mixed with 100.0mL of 1.600 mol/L NaOH. Determine the moles of precipitate which form, and the molarity of each ion (including spectator ions) after the precipitation process is complete. The ksp=(2.5x10^-16) of the precipitate.
Now add 300.0mL of 0.500 mol/L ethylenediammine (addreviated "en") to the above solution. How many moles, if any, of precipitate remain?
kf,[Co(en)3]^2+=8.7x10^13
