This video is about the AP Chemistry Lab Experiment #13: A Spectrometric Determination of Keq of the Iron(III)-Thiocyanate System.

In this video you will learn how to determine the equilibrium constant of a system using Beer-Lambert law. In the video, a spectrophotometer is used to measure the absorbance of the Iron(III)-Thiocyanate solution in order to find the equilibrium concentrations of the system components and the determine Keq.

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

You can refer to the link below to watch a detailed video that explains the Beer-Lambert and its uses.
