What happens when Tollen's Reagent is mixed with Aldehyde?


What is Tollen’s Reagent? How it is prepared? What will happen if we mix it with Aldehyde?


Tollens’ reagent is a chemical reagent most commonly used to determine whether a known carbonyl-containing compound is an aldehyde or alpha-hydroxy ketone.

Aldehydes will be positive in Tollens’ test and a mirror-like material will be formed.

Preparation & Analytical use is given on Wikipedia in detail

Tollens’ test, also known as silver-mirror test, is a qualitative laboratory test used to distinguish between an aldehyde and a ketone. It exploits the fact that aldehydes are readily oxidized (see oxidation), whereas ketones are not.
