Potassium Dichromate 99.8% AR Grade Reagents
Cas Number:7778-50-9
Formula: K2Cr2O7
Molar Mass:294.18
EC Number:231-906-6
Physicochemical properties:
Orange-red glossy crystalline particles or powder. Bitter. It is not hygroscopic or deliquescent (unlike sodium dichromate). When the intense heat is about 500 ° C, it is decomposed into chromium oxide and potassium chromate. It does not work when it is cooled in hydrochloric acid, and chlorine gas when it is hot. Dissolved in 10 parts of cold water or 1.25 parts of hot water, insoluble in ethanol, the aqueous solution is acidic. The relative density (d254) is 2.676. The melting point is 398 ° C (brown liquid).
Usage:
Benchmark the calibration of sodium thiosulfate standard solution. Drip analysis to determine chlorine. Oxidizer. Reagents for chromatography. Organic Synthesis. The liver function jaundice index is measured. Testing stools, etc.
Packing:
500g/25kg
