WebThis is a reaction between a soluble ionic compound (sodium sulfite, Na2SO3) and a covalent compound (chloric acid, HClO3). The balanced equation shows that the reaction produces sodium chloride (NaCl), water (H2O), and sulfur dioxide (SO2). To write the ionic equation, we need to first write the balanced equation in terms of its dissociated ions.
