| has gloss | eng: Sodium amalgam, commonly denoted Na(Hg), is an amalgam, or alloy of mercury, with sodium metal. When metallic sodium is dissolved in mercury, it reacts exothermically to produce the intermetallic compound NaHg2, with enough heat to cause localised boiling of the mercury. This process is normally performed under dry nitrogen gas. This compound is a spongey grey mass, but is also soluble in mercury, allowing a more dilute, liquid amalgam to be produced. |

| has gloss | por: A amálgama de sódio, geralmente denotada como Na(Hg), é uma amálgama que resulta da formação de uma liga de mercúrio com sódio metálico. A amálgama de sódio é uma massa cinzenta esponjosa, solúvel em mercúrio, o que permite a produção, por simples diluição, de amálgamas líquidas. |
