Question #db5d9

Answer 1

Your general chemical equation is

`Cu(OH)_2(s) + 4 NH_3(aq) -> [Cu(NH_3)_4] (OH)_2(aq)`

The ionic equation looks like this:

`Cu(OH)_2(s) + 4 NH_3(aq) -> [Cu(NH_3)_4]^(2+)(aq) + 2OH^(-)(aq)`

Copper (II) hydroxied in ammonia solution is also known as Schweizer's reagent, a chemical used to dissolve cellulose.

`[Cu(NH_3)_4]^(2+)` is the tetraamminecopper (II) ion, a complex ion which I believe is also called cuprammonium ion.

Here's a video on some home-made Schweizer's reagent:
