Best Answer

The Tollen's test is used in organic chemistry to test for the presence of aldehydes. In this reaction, an aldehyde is oxidized to a carboxylic acid while the Ag+ is reduced to silver metal, which deposits as a thin film on the inner surface of the glass.

Cleaning with nitric acid and then washing with hot water will help to remove silver that was deposited earlier.
