What chemical is used to test for starch and what is the result if starch is present?
The chemical is called Iodine solution. If starch is present, the iodine solution will turn from amber to blue black.
What is half saturation test of starch?
With 2ml of starch solution 2ml of saturated ammonium sulphate solution is added. Formation of gelatinous precipitate gives confirmation of presence of starch
What is Iodine solution?
It tests for starch

IKI solution can be detected starch.

Why do you need to add iodine solution to a specimen?
Iodine solution is commonly used to test for starch. If starch is present in a substance (e.g. a leaf which undergone photosynthesis) then the iodien solution would turn blue black. If no starch is present then it remains as light brown.
Add a drop of iodine to both a distilled water test tube and to the test tube containing the starch solution in the test tube What do you observe?
The starch solution will turn black, while the distilled water will remain brown, the same colour as the iodine. This is actually because water, normally used as a control, does not contain any starch and as we know, the iodine test is highly specific for the presence of starch hence no colour change other than iodine dissolving in water to form an iodine solution contrary to starch which we know complexes with iodine, to form starch-iodine complex forming the blue-black colour observed
