| | POTASSIUM CHLOROCHROMATE Usage And Synthesis |
| Chemical Properties | Sparkling, orange-colored
crystalline needles, soluble in glacial acetic acid and acetone.
Undergoes hydrolytic cleavage in water. Heating the salt to 100°C
causes loss of chlorine. | | Uses | Oxidizing agent. | | Preparation | Fifty grams of fine K2Cr2O7 powder is dissolved in a mixture
of 65 ml. of cone. HCl and 50 ml. of water (by heating to 70 °C).
The solution is filtered through a jacketed funnel heated with hot
water. After 1-2 days, the nascent crystals are filtered off with
suction, recrystallized from glacial acetic acid, and dried in a
vacuum desiccator over H2SO4. | | Hazard | Toxic by ingestion and inhalation. |
