This video is about the AP Chemistry InvestigationĀ #11:

What is the Rate Law of the Fading of Crystal Violet Using Beer’s Law?

In this video you will learn how to determine the pseudo-rate order in concentration of Crystal Violet in the presence of sodium hydroxide using Beer-Lambert Law. The reaction between the CV and sodium hydroxide results in a colourless species which will lead to fading the colour of the original solution.

Monitoring the absorbance of CV, we will be able to monitor the change on its concentration during the course of the reaction.

Students studying Chemistry at different levels could highly benefit from this video.
