There are three methods of oxygen production commonly used in the laboratory: one is to make oxygen with potassium chlorate; 2, potassium permanganate oxygen production; Third, hydrogen peroxide produces oxygen (the most common method in the laboratory). Oxygen, with chemical formula O2 and relative molecular weight of 32.00, is a colorless and odorless gas, which is the most common elemental form of oxygen. Melting point -2 18.4℃ and boiling point-183℃. Insoluble in water, about 30ml of oxygen is soluble in 1L water.
Chemical formula of potassium chlorate to produce oxygen: 2KCl03== (catalyst MnO2 is written above the horizontal line).
2KCl+302 (gas lift symbol) Advantages: high utilization rate.
