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.
Participants
| Role | Substance | Coefficient | State |
|---|---|---|---|
| Reactant | Hydrochloric Acid HCl | 1 | (aq) |
| Reactant | Lithium Hydroxide LiOH | 1 | (aq) |
| Product | Water H₂O | 1 | (l) |
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.
