In the future, PLEASE tell us what you are doing. I am guessing that you have added AgNO3 to a Cl solution to ppt AgCl. The reason you add HNO3 is because you want an acid solution from which to ppt AgCl. AgOH and/or Ag2O (actually a hydrated silver oxide) ppts from a neutral or basic solution.
AgNO3(aq) + NaCl(aq) ==> AgCl(s) + NaNO3(aq)
Ag^+ + NO3^- + Na^+ + Cl^- ==> AgCl(s) + Na^+ + NO3^-
Net ionic:
Ag^+(aq) + Cl^-(aq) ==> AgCl(s)
I am really stuck on these 2 questions:
1. Why was 2M HNO3 added before adding 0.05M AgN03?
2.Write a full equation b.) an ionic equation between silver nitrate solution and sodium chloride solution.
