This alkali metal hydride is primarily used as a strong yet combustible base in organic synthesis. NaH is a saline (salt-like) hydride, composed of Na and H ions, in contrast to molecular hydrides such as borane, methane, ammonia, and … See more NaH is produced by the direct reaction of hydrogen and liquid sodium. Pure NaH is colorless, although samples generally appear grey. NaH is ca. 40% denser than Na (0.968 g/cm ). NaH, like See more As a strong base NaH is a base of wide scope and utility in organic chemistry. As a superbase, it is capable of deprotonating a range of even weak See more NaH can ignite spontaneously in air. It also reacts vigorously with water to release hydrogen, which is also flammable, and sodium hydroxide See more Sodium hydride is sold as a mixture of 60% sodium hydride (w/w) in mineral oil.
