We can use a special reagent called Benedict's solution to test for simple carbohydrates like glucose. ... If simple carbohydrates are present these sugars will, when the mixture is heated, reduce the copper and cause a red copper (I) oxide precipitate to form. For this reason, these sugars are known as reducing sugars.

What happens when Benedict's solution is heated?

When Benedict's solution and simple carbohydrates are heated, the solution changes to orange red/ brick red. This reaction is caused by the reducing property of simple carbohydrates. The copper (II) ions in the Benedict's solution are reduced to Copper (I) ions, which causes the color change.

What temperature is Benedict's test?

Benedict's test for reducing sugars

Place the tube in a water bath at about 95°C for a few minutes. Record the colour of the solution.
