How the test is performed by using Benedict's solution?

Answer 1

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. The more red the solution looks, the more copper oxide there is, and therefore the more sugar is in the solution.

Answer 2

The Benedict solution test is used to detect the reducing sugars in a product. The product you are testing will be placed in test tubes, the test tubes should then be placed into a pot of water, and then bring to a boil. If the product turns yellow, orange or green, it has sucrose in it.

Answer 3

benedicts soltuion is a test for "reducing" sugars, one that contains an aldehyde group an "aldose"

Answer 4

Benedict's reagent tests for reducing sugars. A positive test result in a change from clear blue to a dark red precipitate as copper oxide is formed.

Answer 5
