汞俗称水银,银白色,易流动,是在常温下惟一的液体金属。常温下汞不易被氧化,但易蒸发,汞蒸气有毒!加热时氧化为氧化汞。汞有溶解许多金属的能力,所构成的合金统称汞齐。汞不溶于水,易溶于硝酸,也溶于热浓硫酸,但与稀硫酸、盐酸、碱等都不起作用。焙烧含汞矿石可
Mercury commonly known as mercury, silver, easy to flow, is the only liquid metal at room temperature. Mercury at room temperature is not easily oxidized, but easy to evaporate, mercury vapor toxic! Heating oxidation of mercury oxide. Mercury has the ability to dissolve many metals, the composition of the alloy collectively referred to as amalgam. Mercury insoluble in water, soluble in nitric acid, but also soluble in hot concentrated sulfuric acid, but with dilute sulfuric acid, hydrochloric acid, alkali and so does not work. Calcined mercury ore can be
