Formation of Potassium Chloride
2K + Cl2 → 2KCl
Overview
Potassium metal reacts vigorously with chlorine gas to produce potassium chloride. Potassium is even more reactive than sodium, and this reaction occurs with great intensity when the two elements come into contact. The product is a common salt substitute.

Everyday Example
Potassium chloride is sold as a salt substitute for people on sodium-restricted diets, providing a similar salty taste.
Industrial Importance
Potassium chloride is the primary source of potassium for fertilizers (potash). It is also used in the food industry and in medical applications as an electrolyte supplement.
