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 point, and it is not soluble but reactive with all protic organic solvents. It is soluble and nonreactive … Meer weergeven 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 melting point. The dielectric constant Meer weergeven 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. The lump material reacts with humid air, … Meer weergeven LiH reacts violently with water to give hydrogen gas and LiOH, which is caustic.
