The diammide silver complex is an oxidising agent, which is itself reduced to silver metal, which in a clean glass reaction vessel forms a 'silver mirror'. This feature is used as a test for aldehydes, which are oxidised to carboxylic acids.
Once it has been identified that there is a carbonyl group on the organic molecule using 2,4-dinitrophenylhydrazine (also known as Brady's reagent ), Tollens' reagent can be used to ascertain whether the compound is a ketone or an aldehyde.
