Potassium Iodate AR

Potassium iodate AR is a laboratory grade oxidizing agent used in analytical chemistry and controlled chemical reactions.

The “AR” designation indicates it meets stringent quality specifications for use as a primary or secondary standard in quantitative analysis. 

Key Specifications 
Purity (Assay): Typically ≥99.4% to 99.9% (iodometric).
Appearance: White crystalline powder or solid; odourless.
Molecular Weight: 214.00 g/mol.
Solubility: Soluble in water (approx. 9.3g per 100ml at 25°C), insoluble in alcohol.
pH: Generally 5.0–8.0 in a 5% aqueous solution. 

Common Uses 
Analytical Chemistry: Used as an oxidizing agent in iodometric titrations to determine the concentration of thiosulfate, sulfite, arsenic, and zinc.
Food Industry: Used for the iodisation of table salt, especially in tropical regions, because it is more stable than potassium iodide under humid conditions.
Medical/Emergency: Sometimes used as a thyroid-blocking agent in radiation emergencies to prevent the thyroid from absorbing radioactive iodine.
Industrial: Acts as a maturing agent and dough conditioner in commercial baking.
