Benedict’s Quantitative Reagent
Benedict's reagent is used to test for the presence of reducing sugars. Benedict’s quantitative reagent is a modification of qualitative aspects. It contains copper sulphate-sodium carbonate. It also contains potassium thiocyanate and small amount of potassium ferricyanate.The reduction of Cu3+ ions by sugar is a non-stoichiometric equation and is only constant over a small range of sugar concentration.
