Caption: Finding the end point of an iodine titration. At the start of an iodine titration the solution is brown in colour. The titrant, a standard sodium thiosulfate solution of known molarity, is titrated against the iodate solution until it becomes a pale yellow. To help to find an exact end point add a few drops of starch solution to turn it a very dark blue which sharpens the end point. Continue titrating. When the solution becomes a pale blue the end point is very close. The end point occurs when the last trace of blue disappears. The solution is now clear.
