<p>Alex T. Zhao Chul Ou (partner) Greg Kerr IB Chemistry HL 1B January 8, 2013 Solubility Rules Aim: To test the solubility of certain nitrates, chlorides, sulfates, carbonates, bromides, iodides, and hydroxides by mixing the solutions of the sodium salts of above-mentioned anions with solutions containing different cations.
