Reaction of lithium hydride with water
 Synthesis of metal hydride from water - ResearchGate)
With water-containing acids, LiH reacts faster than with water.: 8 Many reactions of LiH with oxygen-containing species yield LiOH, which in turn irreversibly reacts with LiH at temperatures above 300 °C:: 10 LiH + LiOH → Li 2 O + H 2. Lithium hydride is rather unreactive at moderate temperatures with O 2 or Cl 2. See more Lithium hydride is an inorganic compound with the formula LiH. This alkali metal hydride is a colorless solid, although commercial samples are grey. Characteristic of a salt-like (ionic) hydride, it has a high melting … See more LiH is produced by treating lithium metal with hydrogen gas: 2 Li + H2 → 2 LiH This reaction is … See more Hydrogen storage and fuel With a hydrogen content in proportion to its mass three times that of NaH, LiH has the highest hydrogen content of any hydride. LiH is periodically of interest for hydrogen storage, but applications have been thwarted by its … See more • University of Southampton, Mountbatten Centre for International Studies, Nuclear History Working Paper No5. • CDC - NIOSH Pocket Guide to Chemical Hazards See more LiH is a diamagnetic and an ionic conductor with a conductivity gradually increasing from 2×10 Ω cm at 443 °C to 0.18 Ω cm at 754 °C; there is no discontinuity in this increase through the … See more LiH powder reacts rapidly with air of low humidity, forming LiOH, Li2O and Li2CO3. In moist air the powder ignites spontaneously, forming a mixture of products including some nitrogenous compounds.
