In this CLAW (Chemistry Laboratory Alternative Work) At-Home experiment, students will perform an experiment using household chemicals and materials. It was designed as a substitute for in-person laboratories, usually performed at the college level, during the COVID-19 pandemic. However, it may also be used as an experiment that students can carry out in the lab or for student projects.
The objective of this at-home experiment is to demonstrate how the rate of a chemical reaction is temperature-dependent. The reaction of blue food dye with sodium hypochlorite as represented by the following reaction equation: Blue dye (aq) + NaOCl (aq) → Colourless Products (aq) will be carried out at various temperatures in order to evaluate its activation energy.
