Chemistry Projects

Here’s a a sampling of some chemistry projects I did senior year of high school

The Chemical Chameleon

The reaction proceeds as follows:

In solution, NaOH and Sucrose
MnO₄^- –> MnO₄^2- –> MnO₄^3- –> MnO₂

with more intermediates

The sucrose is oxidized and slowly reduces the purple permanganate ion to the green tetraoxidomanganate ion to the blue hypomanganate ion to solid brown manganese dioxide, which is yellow in supspension

Initially pouring the MnO₄

Subsequent color change to blue

Subsequent color change to yellow
