SUMMARY
The reaction time of sodium thiosulfate with hydrochloric acid (HCl) is significantly faster than with sulfuric acid. This difference is attributed to the varying strengths of the acids and their respective ionization in solution. The mechanism involves the formation of sulfur precipitate, which occurs more rapidly with HCl due to its higher reactivity. Observed kinetics indicate that the reaction with HCl follows a first-order rate law, while the reaction with sulfuric acid is slower and less efficient.
