Formation of Potassium Chloride

2K + Cl2 → 2KCl

Visão geral

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.
