How does ammonia react with the solution of cu 2 +?

Answered by admin @ 11/08/2021

Ammonia acts as a Lewis base due to the presence of lone pair of electrons on the nitrogen atom.Therefore,it can form coordinate bond with electron deficient molecules or a number of transition metal cations to from complex compounds.Ammonia reacts with a solution of Cu2+ to from a deep blue coloured complex.The reaction for the above complex can be written as follows:

Cu2+(aq) + 4 NH3(aq) ⇔ [Cu(NH3)4]2+(aq)

Blue Deep Blue

This property of ammonia to form complex compounds is useful in detection of metal ions.
