I'm doing a lab and i'm asked in a pre-lab question to write acomplete equation for each reaction that occurs in the experiment.The ions that we are using are: Ag+, Pb2+, Ca2+, Sr2+, Ba2+, Na+,and K+.

I'm not sure how to do this. Please help! :)

The qualitative analysis experiment you did is actually an abbreviated version of a much larger analysis scheme in which many different cations are separated and identified. Suppose a mixture contains Ag+, K+, NH4+, Hg22+, Pb2+, Mg2+, Sr2+, Ba2+, Cu2+, Al3+ and Fe3+.

(a) Which of the following ions could you separate, by causing them to precipitate, with the addition of HCl? (Hint: HCl is a source of chloride ions. Select all that apply.)

Ag+ K+ NH4+
Hg22+ Pb2+ Mg2+
Sr2+ Ba2+ Cu2+
Al3+ Fe3+
