What is K3N? Important knowledge about K3N

Definition of K₃N
K₃N, also known as Potassium nitride, is a chemical compound with the chemical formula K₃N. Its molecular structure consists of 3 potassium atoms and 1 nitrogen atom. The molecular weight of K₃N is 131.362 g/mol. The ions of K₃N are formed from 3 positive potassium ions and 1 negative nitrogen ion.

Properties of K₃N
2.1. Physical properties of K₃N:
K₃N mostly exists in solid form at room temperature. It has a dark blue color and is odorless. The pH level of a K₃N solution in water is strongly basic.
2.2. Chemical properties of K₃N:
K₃N easily reacts with water to produce ammonia gas (NH₃) and potassium hydroxide (KOH), changing the pH level of the environment.

Typical chemical equations with K₃N:
Because K₃N is strongly basic, it can react with acids to form salts and water. In addition, K₃N can also react with metals and nonmetals depending on the specific conditions of the reaction.

Synthesis of K₃N
4.1. Laboratory synthesis of K₃N:
K₃N can be synthesized through the reaction between potassium and nitrogen gas at high temperatures.
4.2. Industrial synthesis of K₃N:
In industry, K₃N is usually produced through the electrolysis process of sodium nitrate (NaNO₃) solution with a potassium electrode.
