how does benedict's solution work
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.
