In this experiment, students observe what happens when a solution containing silver nitrate (Tollens’ reagent) and a reducing sugar (glucose) react to form silver. As the silver is deposited, students can see a mirror-like coating forming on the inside of the reaction vessel.
Glucose gives silver mirror as a result, with Tollen's ...
Tollens' reagent is a chemical reagent used to determine the presence of an aldehyde, aromatic aldehyde and alpha-hydroxy ketone functional groups. The reagent consists of a solution of silver nitrate and ammonia.

What is a Tollens Reagent? A tollen test is performed to determine the presence of an aldehyde or a ketone in a given unknown solution. This test is named after the German chemist Bernhard Tollens and is also known as the Silver-Mirror Test. Carbonyl compounds are the compounds that contain >C=O as their functional group. These can be either:
