The oxidation number of lithium in lithium nitrate is 1. Formula: LiNO3. Hill system formula: Li1N1O3. CAS registry number: [7790-69-4] Formula weight: 68.946. Class: nitrate. Colour: white. Appearance: crystalline solid.
Lithium hydride is the inorganic compound with the formula Li H. It is a colorless solid, although commercial samples are grey. Li + H 2 â 2 LiH. This reaction is especially rapid at temperatures above 600 Â°C. Addition of 0.001â0.003% carbon, or/and increasing temperature or/and pressure, increases the yield up to 98% at 2-hour residence time.
