WebDetermination of ascorbic acid by potassium iodate. Results are given for a two stage oxidation in the ascorbic acid-KIO 3 reaction under controlled conditions of acidity. The first step corresponds to the Landolt reaction and the second end point is obtained by the classical Andrews method. The reproducibility and accuracy of the results ... Webpotassium iodate, for each titration, with excess potassium iodide. Iodine is liberated from iodate and iodide according to the equation: IO 3-+ 5I-+ 6H + → 3I 2 + 3H 2O The iodine solution, which is a golden-brown colour, can be titrated against sodium thiosulfate solution. The sodium thiosulfate solution is
