HCl + LiOH → LiCl + H2O
Visão geral
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.
Participantes
| Papel | Substância | Coeficiente | Estado |

| Reagente | Hydrochloric Acid HCl | 1 | (aq) |
| Reagente | Lithium Hydroxide LiOH | 1 | (aq) |
| Produto | Water H₂O | 1 | (l) |
Exemplo do cotidiano
Lithium hydroxide canisters in the Apollo spacecraft removed CO₂ from the cabin air, famously becoming critical during the Apollo 13 emergency.
Importância industrial
O LiOH é utilizado na eliminação de CO₂ em naves espaciais e submarinos, em baterias de lítio e como aditivo em lubrificantes. O hidróxido de lítio tem ganhado importância com a expansão da produção de baterias de iões-lítio.
