What happen when potassium chlorate is heated |
| Answer» Decomposition of potassium chlorate:When heated strongly, potassium chlorate decomposes into potassium chloride and oxygen. This reaction is used for the preparation of oxygen.2KClO3 → 2 KCl(s) + 3O2(g)If the decomposition is carried out in the presence of manganese dioxide (MnO2), it takes place at a lower temperature. In this case, MnO2 is used as a catalyst. | |
