I had an unknown solution; I did an anion test for chloride which requires adding 6M HNO3 to 10 drops of my unknown solution until acidic. Then I added 5 drops of 0.1M AgNo3. I found a white precipitate which confirms the present of Cl-.
I further examine the solution by adding 15M NH3 until distinctly basic plus one drop and it shows an intensive blue which confirms the present of Cu2+
How would I write the above reactions into balanced chemical equations?

AgNO3(aq)  & Cl- Rightwards Arrow AgCl(s)  & NO3-

AgCl (s)  & 2 NH3 => [Ag(NH3)2]+    & Cl-

----------

Cu+2  & 4NH3 Rightwards Arrow [Cu(NH3)4]+2
