Chemically, potassium nitrate is a compound composed of three elements: nitrogen, potassium and oxygen. Among them, the atomic relative mass of potassium is 39. 10, that of nitrogen is 14.0 1, and that of oxygen is 16.00. Therefore, the relative molecular weight of potassium nitrate is 39.10+14.01+16.00× 3 =101.
Potassium nitrate is a common inorganic compound with the chemical formula of KNO3. Potassium nitrate is a white crystal, colorless and transparent at room temperature, with high thermal stability and thermal decomposition temperature. It is a chemical widely used in agriculture, medicine and industry.
Potassium nitrate is a commonly used fertilizer in agriculture, which can provide nitrogen and potassium for plants and contribute to their growth and development. In addition, potassium nitrate can also be used in gunpowder and medicine. In industry, potassium nitrate can be used to make glass, fireworks, electronic devices and other products, and can also be used as a catalyst and oxidant for some high-temperature reactions.
Matters needing attention
Because potassium nitrate is a strong oxidizing substance, we should pay attention to safe operation during use to prevent it from reacting with other substances. In addition, potassium nitrate should be protected from moisture and high temperature and humidity during storage, so as not to affect the stability of potassium nitrate.
