Potassium dichromate is a chemical compound with the formula K2Cr2O7. It is a bright orange solid that is soluble in water and commonly used as an oxidizing agent in various chemical reactions.

Potassium dichromate is often used in analytical chemistry as a titrant for the analysis of ferrous and non-ferrous metals. It is also used in organic chemistry as an oxidizing agent for the conversion of alcohols to aldehydes and ketones, as well as for the oxidation of primary amines to nitro compounds.

However, potassium dichromate is a highly toxic and carcinogenic substance, and its use is strictly regulated in many countries due to its hazardous properties. Prolonged exposure to potassium dichromate can cause severe health problems, such as respiratory issues, skin irritation, and eye damage. Therefore, it is essential to handle potassium dichromate with extreme care and always follow appropriate safety procedures.
