- Substance
The physical appearance of potassium dichromate (0.25N) is that of a bright orange liquid, which is characteristic of the dichromate ion. It has a density of 1.01 g/mL, which is typical for aqueous solutions of this nature. The solution is stable under normal conditions but should be stored away from reducing agents and organic materials due to its strong oxidizing nature. It is soluble in water, forming a clear orange solution, and has a pH that can vary depending on concentration but is generally acidic due to the presence of chromate ions.
