Fehling's test formula
WebThe reduction of Cu2+ to Cu+ occurs when Fehling's solution is added to an aldehyde compound, resulting in the reduction of the aldehyde to acids. An orange precipitate forms in this reaction. Tollen's test Sugar reducers and non-sugar reducers are distinguished using the Tollens test. Silver mirror tests are a variation of this test. WebAnswer (1 of 3): It runs something like this: RCHO + 2Cu2+ + 5OH- → Cu2O (s) + RCOO- + 3H2O The reaction is carried out using two separate solutions, aqueous copper (II) sulphate and an alkaline solution of potassium sodium tartrate (usually in sodium hydroxide). When combined, a copper II tart...
