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 , whereas ketones are not.

$H C O O H -$ acts as a reducing agent because it can be easily oxidised to ${C O}_{2}$ and $H_{2} O$ and hence reduces Tollen's reagent.
