What do you mean by Tollens Reagent
Answers
Explanation:
Tollens' reagent is a chemical reagent used to determine the presence of an aldehyde, aromatic aldehyde and alpha-hydroxy ketone functional groups. The reagent consists of a solution of silver nitrate and ammonia. It was named after its discoverer, the German chemist Berhard Tollens. A positive test with Tollens' reagent is indicated by the precipitation of elemental silver, often producing a characteristic "silver mirror" on the inner surface of the reaction vessal.
It has no chemical formula.
Being a mixture of Silver Nitrate and Ammonia in solution. Its active ingredient is Di-ammine-silver(I) complex ( [Ag(NH₃)₂]⁺ ). AlternBatively, aqueous ammonia can be added directly to silver nitrate solution.
