Potassium Dichromate, also known as Potassium Bichromate, Dipotassium Dichromate, and Dichromic Acid-Dipotassium salt, has the chemical formula K2Cr2O7 or Cr2K2O7. Its 0.1N solution appears as an orange clear liquid with no odor and a bitter taste. It is partly soluble in Water but insoluble in Alcohol at ambient conditions.
Potassium Dichromate, 0.5N Solution, Lab Grade is composed of ~2.40 wt.% of pure Potassium Dichromate powder in its aqueous solution. Lab grade chemicals possess reasonable purity but do not comply with any official standard for quality or purity like the ACS Grade, the USP Grade, or the FCC Grade. The Lab Grade is also known as Laboratory Reagent (LR) and Chemically Pure (CP).
