Key Properties
Potassium dichromate 0.02M/L solution is a diluted aqueous solution of potassium dichromate, a strong oxidizing agent widely used in analytical chemistry. This specific concentration is primarily utilized in the determination of chemical oxygen demand (COD) in water testing, a critical parameter for assessing water quality. Potassium dichromate is notable for its ability to oxidize organic matter, making it essential in environmental monitoring and wastewater treatment processes. The solution is prepared to a precise molarity to ensure accurate and reproducible results in laboratory analyses.
Also known as Dichromic acid, dipotassium salt.

The solution appears as a bright orange liquid, characteristic of potassium dichromate due to its hexavalent chromium content. It has a density of approximately 1.06 g/cm³. The boiling point of the solution is around 100 °C, while the freezing point is approximately 0 °C, as it is an aqueous solution. Potassium dichromate is highly soluble in water, with a solubility of about 33 g/100 mL at 20 °C. The solution has a pH of approximately 2, indicating its acidic nature due to the presence of dichromate ions.
