We propose the use of low-cost equipment to replace an UV-Vis spectrometer to study the decay of phenolphthalein as a simple experimental demonstration and valuable tool for the learning of chemical kinetics in different educational levels ranging from junior high to undergraduate students.

In this project the assistants will learn how to produce with a LED and a photoresistance an equipment to measure the rate of a chemical reaction using low cost materials. The results will be contrasted with the ones obtained used with an spectrophotometer UV-Vis. The students and the assistants can perform the data analysis in order to obtain information such as the reaction order and the chemical rate constant for the system adjusting in excel the data properly.
