Sodium Hydride Formula

The preparation of sodium hydride includes a direct reaction between sodium metal and the hydrogen gas. The chemical reaction could be given as below –

2 Na + H2 → 2 NaH

NaH is a colorless and white solid compound with a density of 1.4 g/mL, and a melting point of 800 degree Celsius. Because of the reactivity nature of the compound, it disperses quickly in a mineral oil and safe to handle as well.

Sodium Hydride Chemical Formula

When it exists in pure form, it can quickly ignite the air. At the same time, when it comes in contact with water content available in the air, it becomes flammable hydrogen gas. The compound is a corrosive base and easily hydrolyzed when needed. To prevent fires or explosions NaHis sold as a dispersion in mineral oil and allowing safe handling in air.

NaH + H2O → NaOH + H2

About Sodium Hydride
