Benedict's test


the benedict's solution contains copper 2 ions. When it reacts with reducing sugars like glucose the copper 2 ions turn into copper 1 ions and the colour changes from blue to yellow.

For non reducing sugar like sucrose.
You have to add acid like hydrochloric acid and heat it then neutralise with a base and then perform benedict's test. the procedure would have created glucose and fructose which are reducing sugars so it would react positive to benedic's test
