Answer:
Explanation:Tollens' reagent, also known as silver mirror test, is used to distinguish between aldehydes and ketones. The reagent contains the compound silver nitrate (AgNO3) dissolved in aqueous ammonia (NH3). The reaction involves the reduction of silver ions by the aldehyde to form a silver mirror on the inner surface of the reaction vessel.
The equation for the reaction is as follows:
Aldehyde + Tollens' reagent → Carboxylic Acid + Silver mirror
For example, using formaldehyde (HCHO) as the aldehyde:
HCHO + 2Ag(NH3)2OH → HCOOH + 2Ag + 3NH3 + H2O
