Bromine

溴

Bromine is an easily volatile, dark reddish-brown liquid with a strong disagreeable odor and an irritating effect on the eyes and throat. It produces painful lesions when spilled on the skin.

溴是一种易挥发的暗红棕色液体，具有强烈的难闻气味，对眼睛和喉咙有刺激作用。一旦泄漏到皮肤上，会引起疼痛性损伤。

Hydrogen bromide, HBr, is a colorless gas. In solution with water it forms a strong acid, hydrobromic acid. Reaction with metals or metallic bases produces bromides such as sodium bromide, NaBr and potassium bromide, KBr which are used in medicine. The salt silver bromide, AgBr, is used for making photographic emulsions and appears naturally in the mineral bromargyrite.

氢溴酸（HBr）是一种无色气体。它溶于水形成强酸——氢溴酸。与金属或金属碱反应可生成溴化物，如钠溴化物（NaBr）和钾溴化物（KBr），这些盐用于医药。银溴化物（AgBr）用于制造摄影乳剂，并自然存在于溴化银矿石中。

Bromine occurs in the form of compounds in small quantities in sea water and in natural salt deposits. The element can be released from the bromides by treating them with a strong oxidizing agent such as chlorine.

溴元素以化合物的形式少量存在于海水和天然盐矿中。可以通过用强氧化剂（如氯气）处理溴化物来释放溴元素。
