Name Experiment 5- Post-lab Questions 1. In Reaction B, you observed magnesium metal reacting with a hydrochloric acid solution to produce hydrogen gas and a magnesium chloride solution. Another reaction that has a gaseous product is the reaction of a hydrochloric acid solution (HCl(ag)) with sodium sulfite (Na,so,(ag)) solution to produce a sodium chloride solution (NaCl(aq)) and gaseous sulfur dioxide (S0,(g)). Write a balanced chemical equation for this reaction. 2. The sulfur dioxide produced by aqueous chemistry in the previous...
