| | Peroxydicarbonic acid, dipotassium salt Usage And Synthesis |
| Chemical Properties | white, granular mass; sensitive to light [MER06] | | Physical properties | The monohydrate consists of a white granular mass; starts melting above 200°C; soluble in water, about 15 g/100mL at 20°C; decomposes in boiling water, evolving oxygen. | | Uses | Potassium percarbonate is used in photography under the name “Antihypo” for removing the last traces of thiosulfate from film and paper. It is a strong oxidizing agent in certain chemical analysis; and in microscopic identification of tubercle bacilli. | | Preparation | Potassium percarbonate can be prepared by electrolysis of potassium car-bonate, K2CO3. |
