Starch solution
A solution or suspension of a starch in water. A dilute solution is used to test for elemental iodine. A distinct blue color indicates the presence of iodine in solution.
A 0.4% w/w solution is the standard concentration for a dilute starch indicator solution.
0.4% w/w starch solution is made by adding 4 grams of soluable potato starch to 1 litre of heated water; the solution is cooled before use.
