Silver mirror demo

Replicate the phenomena of German chemist Justus von Liebig’s invention in 1835: the process of silvering glass surfaces. With this unique kit, students will see the oxidation reduction reaction occur as colloidal silver produces and adheres to the inside of the provided Erlenmeyer flask. Students will also perform Tollen’s test for the presence of aldehyes to see if the “reducing sugar structure” needed to form the silver mirror is present. After experimentation, students will be able to see how this process has been applied to significantly improve mirrors used in microscopes and telescopes.
