A test solution is made acid[ic] with dilute nitric acid and treated with silver nitrate solution. A white precipitate forms. What ion was present?

Well, since Ag was involved and AgCl is a white solid (out of the numerous white solids, such as BaSO4, Ca3(PO4)2, and CaC2O4) could Cl- be present?

Thanks. Please reply.

Probably. Could also be Br or I.

Sorry, but colour is not a good enough way to differentiate these precipitates!
