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

The video tutorial explores the rates of reaction through an experiment involving sodium thiosulfate and hydrochloric acid. It covers the setup, procedure, and analysis of results, focusing on how concentration affects reaction speed. The hypothesis tested is whether the time for a cross to disappear is inversely proportional to acid concentration. The video also emphasizes fair testing and safety measures.

How does changing the concentration of hydrochloric acid affect the reaction rate?

What were the results of the experiment regarding the hypothesis?

What variables need to be controlled to ensure a fair experiment?

What safety precautions should be taken during the experiment?
