15. How do you test for the presence of simple sugars? • To test for the presence of simple sugars… use Benedict’s Solution. • Add 5 drops of Benedict’s Solution and heat. • If solution changes to orange, then simple sugars are present. Be n ed i c t s

16. How do you test for the presence of Starch? • To test for the presence of starch… use Lugol’s solution (IKI iodine) • Add 3 drops of Lugol’s solution • If a solutions changes to blue-black, then starch is present. L U G O L S
