The chemical equation 2K2CrO4 -> 2K2Cr2O7 + O2.

1. Detailed information about the equation 2K₂CrO₄ -> 2K₂Cr₂O₇ + O₂ ->

The above equation represents the process of converting Potassium chromate (K₂CrO₄) to Potassium dichromate (K₂Cr₂O₇) and Oxygen. Potassium chromate is bright yellow, while potassium dichromate is orange-red.

2. Reaction conditions

The reaction occurs more easily in an acidic environment, high temperature, and high pressure, which will generate potassium dichromate and oxygen.

3. Reaction process

Potassium chromate (K₂CrO₄) is converted into Potassium dichromate (K₂Cr₂O₇) through the oxidation process. In this process, oxygen atoms from K₂CrO₄ are detached and form oxygen gas.

4. Phenomena observed

When the reaction occurs, one can see the color of the liquid changing from yellow of potassium chromate to orange-red of potassium dichromate. At the same time, oxygen gas is produced.
