What is K2NO3? Important knowledge about K2NO3.

Definition of K₂NO₃:
1.1 Name: K₂NO₃ is commonly known as Potassium Nitrate.
1.2 Atomic composition: A K₂NO₃ molecule consists of 2 Potassium (K) atoms, 1 Nitrogen (N) atom, and 3 Oxygen (O) atoms.
1.3 Atomic mass: The atomic mass of K₂NO₃ equals the total mass of the atoms that compose it, including: 2 Potassium atoms (39.10 g/mol per atom), 1 Nitrogen atom (14.01 g/mol), and 3 Oxygen atoms (16.00 g/mol per atom).
1.4 Ionic structure: K₂NO₃ dissociates in solution into K+ and NO₃- ions.

Properties of K₂NO₃:
2.1 Physical properties: Potassium Nitrate is a white, odorless solid with a neutral or slightly alkaline pH.
2.2 Chemical properties: Potassium Nitrate is non-flammable but can enhance the combustion of other substances. It decomposes at high temperatures, producing potassium nitrite and oxygen.

Common chemical reactions of K₂NO₃: Potassium Nitrate can react with strong acids like sulfuric acid, producing nitric acid and potassium sulfate.

Synthesis of K₂NO₃:
4.1 Laboratory synthesis: Potassium Nitrate is usually synthesized by reacting potassium hydroxide with nitric acid.
4.2 Industrial synthesis: In industry, Potassium Nitrate is typically produced from the reaction between potassium chloride and sodium nitrate.
