About POTASSIUM DICHROMATE 0.02 M-L SOLUTION FOR DETERMINATION OF COD

Potassium Dichromate 0.02 M-L Solution is a crucial tool for Chemical Oxygen Demand (COD) determination in water testing. This orange-red liquid, bitter-tasting solution is an AR-grade analytical reagent prepared with a purity of exact 0.02 M concentration. It serves as a highly soluble oxidizing agent, ideal for laboratories quantitative chemical analysis. With a molecular weight of 294.18 g/mol and a density of 2.68 g/cm3, this solution must be stored away from incompatible materials due to its corrosive and carcinogenic properties. Its shelf life of two years and acidic pH level ensure reliable performance, making it a must-have for accurate COD testing.
