hey frnd here ur best answer. .

k2cr2o7 is potassium disghcromate
most commonly used as an oxidizing agent in various laboratory and industrial applications.
, it is acutely and chronically harmful to health.
It is a crystalline ionic solid with a very bright, red-orange color
This color change arises because the aldehyde can be oxidized to the corresponding carboxylic acid. A ketone will show no such change because it cannot be oxidized further, and so the solution will remain orange.
When heated strongly, it decomposes with the evolution of oxygen.
4K2Cr2O7 → 4K2CrO4 + 2Cr2O3 + 3O2
When an alkali is added to an orange red solution containing dichromate ions, a yellow solution is obtained due to the formation of chromate ions. For example, potassium chromate is produced industrially using potash:
K2Cr2O7 + K2CO3 → 2 K2CrO4 + CO2
