Question 3 What is the reaction order for the decomposition of p-toluenesulfinic acid? 3 CH3C6H4SO2Hiag) → (CH3C6H4)2SO2Stac) + CH3C6H4SO3Hag) + H2O Zero One Two Three We cannot tell from this information alone. Question What is the purpose for including starch in the sodium thiosulfate solution? It stabilizes the thiosulfate to keep it from oxidizing when exposed to air. It acts as a catalyst to increase the reaction rate so the experiments can be completed in the lab period. O The dark blue colour of the starch complex disappears and the solution becomes colourless when the reaction has reached its endpoint.
