Potassium iodide is White cubic crystal or powder. In the humid air slightly hygroscopic, long time to precipitate free iodine and become yellow, and can form a trace of iodate. Light and moisture can accelerate decomposition. 1 g was 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. The aqueous solution is neutral or slightly alkaline, can dissolve iodine. Its aqueous solution will be oxidized and gradually yellow, can add a small amount of alkali to prevent. The relative density of 3.12. Melting point 680 ° C. The boiling point of 1330 ℃. Approximate lethal dose (rat, vein) 285mg. Widely used in capacity analysis of iodometric method in the preparation of titration solution. Haploid breeding in the preparation of Bledes, improved white, MS and RM and other media. Stool test and so on. Camera. Pharmaceuticals,Feed. If the experiment does not dissolve or temperature reasons, please adjust the appropriate.
