    investigate the oxidation number of a metal that would form aqueous ions when reacted with an aqueous nitrate salt. For this purpose‚ we chose to investigate the reaction of solid copper metal‚ in the form of a wire‚ with aqueous silver nitrate. Before we began the lab‚ we hypothesized that when silver nitrate‚ AgNO3‚ reacts with copper‚ Cu‚ the oxidation number of silver (Ag) ions that form will be +1. The unbalanced chemical equation that we used to represent this reaction is Cu + AgNO3 → Ag + Cu(NO3)2
