Hydrochloric Acid and Lithium Hydroxide

HCl + LiOH → LiCl + H2O

Overview

Hydrochloric acid reacts with lithium hydroxide to form lithium chloride and water. Lithium hydroxide is used as a CO₂ absorbent in spacecraft and submarines because it reacts with CO₂ more efficiently per unit mass than other alkali hydroxides, critical where weight is a constraint.

Everyday Example

Lithium hydroxide canisters in the Apollo spacecraft removed CO₂ from the cabin air, famously becoming critical during the Apollo 13 emergency.

Industrial Importance

LiOH is used in CO₂ scrubbing for spacecraft and submarines, in lithium battery cathode production, and as a grease thickener.
