Final answer:
Tollens' reagent is an alkaline solution of silver (Ag) ion complexed with ammonia (NH3) that is used to test for aldehydes. It forms a silver mirror on a clean glass surface when it reacts with an aldehyde.
Step-by-step explanation:
Tollens' reagent is an alkaline solution of silver (Ag) ion complexed with ammonia (NH3). Tollens' reagent is an alkaline solution of silver (Ag) ion complexed with ammonia (NH3) that is used to test for aldehydes. It forms a silver mirror on a clean glass surface when it reacts with an aldehyde.
It is used to test for the presence of aldehydes. When Tollens' reagent reacts with an aldehyde, the Ag+ ion is reduced to free silver (Ag), which is deposited on a clean glass surface, producing a silver mirror.
Ketones do not react with Tollens' reagent. Tollens' reagent is an alkaline solution of silver (Ag) ion complexed with ammonia (NH3) that is used to test for aldehydes. It forms a silver mirror on a clean glass surface when it reacts with an aldehyde.
