Potassium Chromate vs. Potassium Dichromate: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Published on December 25, 2023
Potassium chromate (K2CrO4) is a yellow compound, less oxidizing, whereas potassium dichromate (K2Cr2O7) is a red-orange compound, more oxidizing.

Key Differences

Potassium chromate consists of potassium ions and chromate ions (CrO4)2-, forming a yellow compound. Potassium dichromate contains potassium ions and dichromate ions (Cr2O7)2-, resulting in a red-orange compound.
