Sodium hydride

<p>Sodium hydride is the <a href="/facts/Chemical_compound/37FXqqtv">chemical compound</a> with the <a href="/facts/Empirical_formula/xd0vSIlm">empirical formula</a> <a href="/facts/Sodium/eYuSPu2V">Na</a><a href="/facts/Hydrogen/BoYHjl0J">H</a>. This <a href="/facts/Alkali_metal_hydride/v2rlBGMg">alkali metal hydride</a> is primarily used as a strong yet combustible <a href="/facts/Base_(chemistry)/M9wA7qeM">base</a> in <a href="/facts/Organic_synthesis/aprl6Iq7">organic synthesis</a>. NaH is a saline (salt-like) <a href="/facts/Hydride/v2rlBGMg">hydride</a>, composed of Na+ and H− ions, in contrast to molecular hydrides such as <a href="/facts/Borane/pHQMPw5r">borane</a>, <a href="/facts/Silane/XNevDLgE">silane</a>, <a href="/facts/Germane/BDKb4Wxl">germane</a>, <a href="/facts/Ammonia/MtLtJFtz">ammonia</a>, and <a href="/facts/Methane/kBHneYnh">methane</a>. It is an ionic material that is insoluble in all solvents (other than molten sodium metal), consistent with the fact that H− ions do not exist in solution.
