Today we will be doing a demonstration of the Tollen's test and use it to make a silver mirror.
The Tollen's test is mainly used to identify aldehyde groups (forms a silver mirror) and it was historically used a lot. It was slowly replaced with more accurate and better techniques. However, it is still very useful for hobbyist who can't afford big expensive machines. The silver mirror is kind of an off-shoot of the Tollen test, where all we are after is the mirror that forms. We use glucose because it is a cheap and easy aldehyde source.
In the future, I might make a video where I identify an uknown chemical using a series of classic techniques.
