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.
They cause the Cu 2+ in the Benedictâs reagent to become reduced (gain electrons) to form Cu 1+ , forming Cu 2 O. The reaction occurs when the mixture is heated to 100 Â°C. Continue Carbohydrates continued Testing for reducing sugarsThe test tube rack contains substances that were tested in lab.
