Learning Objectives

Students should:
$know reactions, including ionic equations where appropriate, for identifying: i carbonate ions, CO₃²⁻, and hydrogencarbonate ions, HCO₃⁻, using an aqueous acid to form carbon dioxide ii sulfate ions, SO₄²⁻, using acidified barium chloride solution iii ammonium ions, NH₄⁺, using sodium hydroxide solution and warming to form ammonia Tests for halide ions and for the ions of Group 1 and 2 metals are also required, but are covered elsewhere in this Topic.$
