Figure 1: Complex ions containing bound
water and ammonia.
The structure of Cu2+ ion in water is on the left.
Note that the water molecules are bound,
through oxygen atoms,to the copperion.
In this experiment you will make a compound
that has NH3
molecules bound to the copper(II)
ion through N atoms, similar to the complex
ion [Co(NH3)
