Rates of Reaction Experiments: Investigating the Relationship between Concentration and Reaction Time

This is a lecture presentation on rates of reaction experiments. The presenter discusses the concept of the rate of a reaction and how it can be measured. The focus of the experiment is on investigating the relationship between the concentration of hydrochloric acid and the rate of the reaction between that acid and sodium thiosulfate. The presenter explains how the experiment is conducted, with Matt mixing the two reactants and measuring the time it takes for the cross to disappear. The presenter also discusses the hypothesis being tested and how the results will be plotted on a graph. The experiment's fairness is also discussed, including controlling variables and ensuring safety measures are in place. Finally, the conclusion is drawn from the experiment results, and the presenter recaps the method used.
