Experiment #5: Formation and Naming of Ionic Compounds Objective: In this experiment, we focus on 4 objectives. First, we will cause the formation of an ionic compound by mixing a cation and an anion. Then we will learn how to write the formula for an ionic compound and be able to properly name them. Lastly, we will identify an unknown anion by comparing it’s properties to those of known anions. Often, mixing cations and anions will result in a chemical reaction. It can result in a visible reaction, like producing gas or a solid, or non-visible like changing from an acid to a base or vice versa. Reactions can be classified as: 1) Cation+Anion -> Precipitate (Solid) 2) Cation+Anion -> Gas (G) 3) Cation & Anion -> No Reaction (NR) Equipment and Reagents: Two well plates pHydrion paper 3M HCl 0.25M solution of Anions Cl-, OH-, CO2- 3, SO2- 4, PO3- 4 0.25 M solution of Cations H+, Al3+, Ba2+, Cu2+, Fe3+
