Description
- General description: Potassium nitrate is colorless potassium salt having rhombic crystals. It is an oxidizing agent. In nature it is found as saltpeter. It can be prepared by reacting potassium carbonate/ hydroxide with nitric acid or by the reaction of sodium nitrate with potassium chloride.1 It can be prepared by combining ammonium nitrate and potassium hydroxide under hot conditions.Potassium nitrate can find applications as an oxidizer, which can be prepared by combining ammonium nitrate and potassium hydroxide under hot conditions.[1]
- Application: Potassium nitrate may be employed for the following studies:Preparation of gun powder, ceramics, glass, dyeing and printing.1 As oxidizing agent in the fireworks.1Preparation of potassium nitrite.1As desensitizing agent for tooth hypersensitivity.[2]As phase change material for the preparation of nanofluids with phase change behavior.[3]
