SDS GHS, MSDS Sheet of Potassium Iodate
Potassium Iodate BP Grade
Potassium Iodate contains not less than 99.0% and not more than 101.0% of KIO3, calculated with reference to the dried substance.
A white crystalline powder.
Slowly soluble in water; insoluble in ethanol (96%).
Dissolve 10 g of the substance being examined in sufficient water to produce 200 ml (solution S1).
Add 25 ml of hydrochloric acid to 6 g of the substance being examined, evaporate to dryness and repeat. Heat until iodine is removed. Dissolve the residue in 2.5 ml of a 25% v/v solution of hydrochloric acid and dilute to 50 ml with water (solution S2).
A. 1 ml of solution S1 yields reaction B characteristic of potassium salts.
B. Dissolve 0.1 g in 5 ml of water. Add 1 ml of silver nitrate solution followed by 1 ml of sulphur dioxide solution. A yellow precipitate is produced immediately.
Acidity or alkalinity: pH of solution S1, 5.0 to 8.0.
Clarity and colour of solution: Solution S1 is clear and colourless.
Chloride, chlorate, bromide, bromate: Dilute 5 ml of solution S1 to 15 ml with water, add 20 ml of sulphur dioxide solution and heat on a water bath for 30 minutes. Heat to boiling, cool, add 10 ml of 18M ammonia and 20 ml of silver nitrate solution R2 and dilute to 70 ml with water. Filter, transfer 35 ml of the filtrate to a Nessler cylinder and acidify with 6 ml of nitric acid . After 5 minutes, any opalescence, when viewed vertically, is not greater than that produced by treating 5 ml of a 0.00165% w/v solution of sodium chloride at the same time and in the same manner (0.02%).
Iodide: Add 1 ml of 1.8M sulphuric acid to 25 ml of solution S1 and shake with 1 ml of chloroform. Any violet colour produced is not more intense than that of a solution prepared at the same time and in the same manner but using 5 ml of solution S1 and 2 ml of iodide standard solution (10 ppm I) (20 ppm).
Sulphate: Add 1 ml of a 25% w/v solution of barium chloride to 1.5 ml of sulphate standard solution (10 ppm SO4), shake and allow to stand for 1 minute. Add 12.5 ml of solution S2 diluted to 15 ml with distilled water and 0.5 ml of 5M acetic acid and allow to stand for 5 minutes. Any opalescence produced is not more intense than that of a standard prepared in the same manner but using 7.5 ml of sulphate standard solution (10 ppm SO4) diluted to 15 ml with distilled water in place of the solution being examined (50 ppm).
Heavy metals: Adjust the pH of 20 ml of solution S2 to about 5 with 5M ammonia. The solution complies with limit test A for heavy metals, Appendix VII. Use 10 ml of lead standard solution (2 ppm Pb) to prepare the standard (20 ppm).
Loss on drying: When dried at 130° for 1 hour, loses not more than 0.5% of its weight. Use 1 g.
To 1.5 g add sufficient water to produce 250 ml. To 25 ml of the resulting solution in an iodine flask add 3 g of potassium iodide, 100 ml of water and 10 ml of hydrochloric acid . Close the flask and stand in the dark for 5 minutes. Titrate the solution with 0.1M sodium thiosulphate VS to a light straw colour and then complete the titration to a colourless end point using starch mucilage as indicator. Each ml of 0.1M sodium thiosulphate VS is equivalent to 3.567mg of KIO3.
Potassium Iodate FCC Food Grade
Potassium Iodate occurs as a white, crystalline powder. One gram dissolves in about 15 mL of water. It is insoluble in alcohol. The pH of a 1:20 aqueous solution is between 5 and 8.
Function: Maturing agent; oxidizing agent; dough conditioner.
Identification: Add 1 drop of starch TS and a few drops of 20% hypophosphorous acid to 1 mL of a 1:10 aqueous solution. A transient blue color appears.
Assay: Not less than 99.0% and not more than 101.0% of KIO3 after drying.
Chlorate: Passes test (limit about 0.01%).
Iodide: Passes test (limit about 0.002%).
Lead: Not more than 4 mg/kg.
Loss on Drying: Not more than 0.5%.
Assay: Dissolve about 1.2 g of sample, previously dried at 105C for 3 h and accurately weighed, in about 50 mL of water in a 100-mL volumetric flask, dilute to volume with water, and mix. Transfer 10.0 mL into a 250-mL glass-stoppered flask, add 40 mL of water, 3 g of potassium iodide, and 10 mL of 3:10 hydrochloric acid, and stopper the flask. Allow to stand for 5 min, add 100 mL of cold water, and titrate the liberated iodine with 0.1 N sodium thiosulfate, adding starch TS near the endpoint. Perform a blank determination (see General Provisions), and make any necessary correction. Each milliliter of 0.1 N sodium thiosulfate is equivalent to 3.567 mg of KIO3.
Chlorate: Add 2 mL of sulfuric acid to 2 g of sample contained in a beaker. The sample remains white, and no odor or gas evolves.
Iodide: Dissolve 1 g of sample in 10 mL of water and add 1 mL of 2 N sulfuric acid and 1 drop of starch TS. No blue color appears.
Lead: Determine as directed in the Flame Atomic Absorption Spectrophotometric using a 10-g sample.
Loss on Drying: Determine as directed under Loss on Drying, drying a sample at 105° for 3 h.
