Positive control is starch here and water is the negative control.
Which substance should have and should have not the starch is demonstrated by the controls in lab. Saliva is included here because saliva contains amylase which breaks down the starch.
Starch Solution is the positive control for starch. In the presence of Starch, IKI (Potassium Iodide) will turn purple in the presence of control solution i.e., Starch. This is demonstrated by this.
If we perform experiment with the water then it will be an example of negative control as due to the absence of starch in water. Our Saliva contains amylase which breaks down starch into glucose which will turn the IKI into yellow/brown when exposed to the amylase.
