Simple Answer. Benedict's solution contains copper sulfate that reacts with sugar to form copper oxide, a reddish brown powder. The more red the solution looks, the more copper oxide there is, and therefore the more sugar is in the solution.More Complicated Answer. Reducing sugar is oxidized when heated with Benedict's solution, which means the sugar looses electrons. Benedict's solution contains copper sulphate.The copper 2+ ions in copper sulfate gain an electron that the sugar has lost and become copper 1+ ions-this is called reduction. The copper ions immediately react with oxygen to form copper oxide which forms a reddish brown precipitate.he more red the solution looks, the more copper oxide there is, and therefore the more sugar is in the solution. More Complicated Answer. Reducing sugar is oxidized when heated with Benedict's solution, which means the sugar looses electrons. Benedict's solution contains copper sulphate.
All monosaccharides and some disaccharides such as lactose and maltose are called reducing sugars. When Benedictâs test is positive, an orange-red precipitate forms when the Benedictâs reagent is added to a solution contain reducing sugar. The iodine test is a chemical test for starch. When iodine solution which is red is added to starch it turns blue/black in colour. If according to your question,... Benedictâs test is used to detect the presence of reducing sugars.
