Based upon the precipitation of silver chloride, gravimetric methods have long been used for the determination of chlorine. It is, however, difficult to collect and weigh the small quantity of silver chloride obtained from rocks containing 0.05 per cent or less of chlorine. The introduction of ...
在化学元素的瑰宝中，卤素(Halogen)家族独树一帜，由五位成员组成：活泼的氟( Fluorine )、活泼的氯( Chlorine )、神秘的溴( Bromine )、珍贵的碘( Iodine )，以及极其罕见的砹(Astatine)。这些元素位于第七主族，以其独特的化学性质，轻松与其它元素形成化合物，创造出无数神奇的化学反应。卤素化合...

2 The halogens, chlorine, bromine and iodine, and their compounds, show a variety of similarities and trends in their physical and chemical properties.(a)(i) Give the colours and states of chlorine, bromine and iodine at room temperature and pressure.halogen colour state chlorine bromine iodine...
Most of the chlorine produced is used in the manufacture of chlorinated compounds for sanitation, pulp bleaching, disinfectants, and textile processing. Further use is in the manufacture of chlorates, chloroform, carbon tetrachloride, and in the extraction of bromine. Organic chemistry demands much ...
Chlorine has all the oxidation numbers varying from -1 to +7. Further, it is a highly reactive gas. It can release bromine and iodine from bromide and iodide salts, respectively. Therefore, it has the ability to oxide the anions of elements which are located below chlorine in the periodic...
- Fluorine (F) - most reactive - Chlorine (Cl) - Bromine (Br) - Iodine (I) - least reactive 4. Compare Chlorine with Other Halogens: Since chlorine is positioned below fluorine and above bromine and iodine in the group, it is more reactive than bromine and iodine but less reactive tha...
5.2.7 Chlorine, Bromine and Iodine Chloryl fluoride, ClO2F, is the most common chlorine oxide fluoride and is commonly encountered in the reactions of the binary chlorine fluorides ClF, ClF3 and ClF5 with oxides and hydroxides. It is most conveniently prepared in high yield by the reaction of...
