Detailed explanation-1: -Benedict’s solution contains copper (II) sulphate and the Cu2+ ions are what give the solution its blue colour. If simple carbohydrates are present these sugars will, when the mixture is heated, reduce the copper and cause a red copper (I) oxide precipitate to form.
Detailed explanation-2: -Sugar presence in a sample of urine can be detected by performing the following two tests: Benedict’s test. Fehling’s test.
