Signs and symptoms of spasticity include: 1  muscle tightness. 2  joint stiffness. 3  involuntary jerky movements.  exaggeration of 1  reflexes. unusual posture.  abnormal positioning of fingers, wrists, arms, or 1  shoulders. muscle spasms.  involuntary crossing of the legs, called scissoring because the legs cross like the tip of a pair of scissors.
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.
You have a solution which you know contains sugar but you do no know whether it is reducing sugar, non-reducing sugar or a mixture of both. First, carry out the test for reducing sugar. if this is negative, then test for non-reducing sugar. If it is positive, ensure that you have added excess Benedict's reagent, that is ensure that all of the reducing sugar has reacted. Then filter the contents of the tube, and save the filtrate.
