Lithium Reacting with Water

2Li + 2H2O → 2LiOH + H2

Visão geral

Lithium reacts steadily with water to produce lithium hydroxide and hydrogen gas. While still vigorous, lithium is the least reactive of the alkali metals due to its high ionization energy and strong metallic bonding. The hydrogen does not ignite spontaneously as with sodium or potassium.

Exemplo do cotidiano

Lithium's moderate water reactivity is why lithium-ion batteries, while reactive, are generally safer to handle than metallic sodium or potassium.

Importância industrial

O hidróxido de lítio é um material crítico para o fabrico de cátodos de baterias de iões de lítio e como absorvente de CO₂ nos sistemas de suporte de vida de naves espaciais.
