WebFehling's solution; Using Tollens' Reagent - The Silver Mirror Test. Tollens' reagent contains the silver(I) complex ion [Ag(NH 3) 2] + This is formed when aqueous ammonia is added to a solution of silver nitrate. Tollens' reagent is also known as ammoniacal silver nitrate; If gently warmed with Tollens' reagent, an aldehyde will become oxidised WebAnswer (1 of 3): Okay I will explain this here. First of all we know that group i.e. aldehyde gives positive test with Fehling’s solution whereas ketones don't give positive test with it.
