Question:

How is the presence of glucose (sugars) tested?

Author: Alana Ray



Answer:

The presence of the glucose is tested by placing (2cm cubed of) the food solution into a test tube and adding 10 drops of Benedict solution to it, which is a blue colour. After this place the test tube into a beaker and half fill the beaker with hot water, now leave it for 5 minutes. If the presence of sugar is high the solution will turn brick-red, if it’s moderately present the solution will turn yellow and if the presence is low it will turn green
