Question

Hi,
I have to plan an experiment to compare quantitatively, the amount of glucose in fresh samples of orange, lemon and grapefruit juice.

Thank you - just need an idea of where to start!

Answer 1

You can use the glucometer, but you can also use pH test paper to determine the concentration of the glucose in each solution. Because glucose is acid, use red Ph test paper. If it's more red, it means that more glucose in there.

Answer 2

Use a glucometer squeeze your juices onton a test trip and stick in glucometer for a reading.
