Amylase is an enzyme that hydrolyses starch into maltose. Starch reacts with iodine in potassium iodide solution to produce a blue-black colour. Amylase has an estimated optimum temperature of 40 ∘C40\text{ }^\circ\text{C}40 ∘C.
Devise a method a student could use to confirm that the optimum temperature for amylase is 40 ∘C40\text{ }^\circ\text{C}40 ∘C.
