Experiment on How Increasing Reactant Concentration Affects Reaction Rate

The video tutorial explores an experiment to investigate how increasing the concentration of a reactant affects the reaction rate by observing sulfur precipitate formation. The hypothesis, based on collision theory, suggests that the reaction rate is proportional to the concentration of hydrochloric acid. The experiment involves mixing sodium thiosulfate and hydrochloric acid, observing the cloudiness due to sulfur precipitate, and measuring the time taken for the cross to disappear. The results, plotted on a scatter graph, show a linear relationship, confirming the hypothesis.
