Potassium Iodide 99% AR Grade Reagent
Cas Number:7681-11-0
Formula: KI
Molar Mass:166
EC Number:231-659-4
Physicochemical properties:
White cubic crystal or powder. It is slightly hygroscopic in humid air, precipitates free iodine for a long time and turns yellow, and can form trace amounts of iodate. Light and moisture can accelerate decomposition. 1 g is dissolved in 0.7 ml of water, 0.5 ml of boiling water, 22 ml of ethanol, 8 ml of boiling ethanol, 51 ml of absolute ethanol, 8 ml of methanol, 7.5 ml of acetone, 2 ml of glycerol, and about 2.5 ml of ethylene glycol. Its aqueous solution is neutral or slightly alkaline and can dissolve iodine.
Usage:
A titration solution is prepared in a volumetric analysis iodometric method. Mediums such as Beredes, Modified White, MS and RM are prepared in haplotypes. Fecal examination, etc. Take a photo. Pharmaceutical.
Packing:
500g/25kg
