Potassium Iodate is an oxidizing agent and as such it can cause fires if in contact with combustible materials or reducing agents. It is sometimes used for iodination of table salt to prevent iodine deficiency. Because iodide can be oxidized by molecular oxygen to iodine under wet conditions, US companies add thiosulfates or other antioxidants to the potassium iodide. Potassium iodate may be used to protect against accumulation of radioactive iodine.

DEFINITION
Potassium Iodate contains not less than 99.0% and not more than 101.0% of KIO3, calculated with reference to the dried substance.

CHARACTERISTICS
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).

IDENTIFICATION
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.

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.

ASSAY
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.

DESCRIPTION
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.

REQUIREMENTS
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%.

Fire Extinguishing Media: Water spray, Foam. Use means suitable for extinguishing surrounding fire. Avoid carbon dioxide and gas filled extinguisher. Water should be preferred.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures under fire conditions, it may produce toxic or irritating fumes. Fire-extinguishing work is done from the windward and the suitable fire-extinguishing method according to the surrounding situation is used. Uninvolved persons should evacuate to a safe place.

Personal precautions, protective equipment and emergency procedures: Avoid breathing dust/fumes/gas/mist/vapors/spray. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Restrict unprotected personnel from the area. Prevent any contact with hot surfaces. Do not approach facing the wind. Do not touch the spilled material.
Environmental precautions: Do not let the product enter drains, soil or water sources.
Methods and materials used for containment Cleanup procedures and Storage:
Small Spill: Eliminate all sources of ignition. Avoid dust formation. Avoid breathing dust. Ensure adequate ventilation. Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements.
Large Spill: Eliminate all sources of ignition. Do not let the product enter drains. Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow evacuating through the sanitary system if local laws permit.

Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. In case of insufficient ventilation, wear suitable respiratory equipment. Wash thoroughly after handling. Do not drink, eat or smoke while handling. Avoid contact with skin, eyes and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Prevent any contact with hot surfaces.
Conditions for safe storage, including any incompatibilities: Store in cool <32C, dry and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Do not leave the material container open. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid contact with skin and eyes. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like organic substances, strong reducing agents, acids, powdered metals, strong bases, alcohols, phosphorous, anhydrides, halogens, acids metal powders and heat, combustible substances.

Airborne Exposure Limits: None established. Limit.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Dust deposits on floors and other surfaces may pick up moisture and cause the surfaces to become slippery and present safety hazards. Handle in accordance with good industrial hygiene and safety practice. Wash hands after handling.
