Sodium thiosulfate solution reacts with dilute hydrochloric acid to form a cloudy precipitate of sulfur.
Na2S2O3(aq)+2HCl(aq)→2NaCl(aq)+H2O(l)+S(s)+SO2(g) \text{Na}_2\text{S}_2\text{O}_3(\text{aq}) + 2\text{HCl}(\text{aq}) \rightarrow 2\text{NaCl}(\text{aq}) + \text{H}_2\text{O}(\text{l}) + \text{S}(\text{s}) + \text{SO}_2(\text{g}) Na2S2O3(aq)+2HCl(aq)→2NaCl(aq)+H2O(l)+S(s)+SO2(g)A student wants to investigate how the rate of this reaction is affected by temperature. They plan to use the 'disappearing cross' experiment.
Devise a method the student could use to obtain a range of results at different temperatures.
