answered-by-expert Expert Answer

The oxidation of aldehydes can be performed with a mild oxidizing agent, such as Ag+  in
ammonia solution used in the Tollens test or Cu2+  in alkaline solution used in Fehling's test.  If
the Tollens test is performed in a scrupulously clean glass vessel, the silver metal is plated on the
walls of the glass to form a silver mirror.  Fehling's reagent is a deep blue Cu2+  solution that
forms a brick-red precipitate of Cu2O in the presence of aldehydes.
