Brief Overview
Potassium dichromate, also called potassium dichromate (VI), is an orange-colored crystalline toxic inorganic chemical. It occurs naturally in mineral form as lopezite, which is a very rare mineral.
Manufacturing Process
Potassium Dichromate is industrially manufactured by the reaction of potassium chloride solution (KCl) with sodium dichromate (Na2Cr2O7) as shown:
Na2Cr2O7 + 2 KCl → K2Cr2O7 + 2 NaCl
Potassium Dichromate can also be obtained from its related compound, potassium chromate (K2CrO4), which reacts with acids to give the dichromate salt.
