When sodium thiosulfate reacts with hydrochloric acid, one of the products produced is sulfur dioxide gas (SO2). Another product is sodium chloride (NaCl), while water (H2O) is also produced. The balanced chemical equation for this reaction is:
Na2S2O3 (aq) + 2HCl (aq) → 2NaCl (aq) + SO2 (g) + H2O (l) + S (s)
Na2S2O3 (aq) + 2HCl (aq) → 2NaCl (aq) + SO2 (g) + H2O (l) + S (s)
