Sodium Hydride is a strong base/alkali. It is an inorganic salt comprising of positively charged sodium ions, and negatively charged hydride (hydrogen) ions: Na+H-. It is a good source of the uncommon hydride ion.
(NB Sodium hydride, NaH, is different to Sodium HYDROXIDE, NaOH, which is common table salt.)
Adding sodium hydride to ethanol would produce sodium ethoxide and hydrogen gas. Sodium hydride is a strong base and will react with ethanol to form the ethoxide salt and release hydrogen gas as a byproduct.
A hydride is hydrogen anion (a negative ion), written as H- A few examples of hydrides are Sodium hydride, NaH Calcium hydride, CaH2 Sodium borohydride, NaBH4 Lithium aluminum hydride, LiAlH4
Melting and decomposition at about 800 0C.
The formula for sodium hydride is simply NaH. This compound is formed by the reaction between sodium metal and hydrogen gas. When exposed to water, sodium hydride reacts vigorously to form H2(g), Na+ and OH-.
The conjugate acid is Hydrogen (H2), the pKa of which is 35.

Sodium hydride is an ionic compound.
When hydrogen reacts with sodium, it forms hydrogen gas and sodium hydride. The chemical equation for this reaction is 2Na + 2H2 -> 2NaH. Sodium hydride is a white solid that is highly reactive with water.

Hydrogen and sodium can make sodium hydride, NaH.

Sodium chloride is NaCl; if you think to sodium hydride this is NaH.
The ionic compound for sodium hydride is NaH. In this compound, sodium (Na) donates one electron to form a cation with a +1 charge, and hydrogen (H) accepts this electron to form an anion with a -1 charge. The resulting ionic compound is held together by electrostatic forces of attraction between the positively charged sodium ion and the negatively charged hydride ion.
