A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near ...

Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit ...

sodium + chlorine → sodium chloride magnesium + oxygen → magnesium oxide calcium + chlorine → calcium chloride lithium + oxygen → lithium oxide In all of these reactions, the metal atoms ...

The solution turns brown. This brown colour is the displaced bromine. The chlorine has gone to form sodium chloride.

The team was also able to show that the resulting SAC-like structures are selective—if water and chloride ions are in the reaction environment at the same time, only gaseous chlorine is formed.

One pathway for the production of active chlorine is the photolysis of nitryl chloride into chlorine and nitrogen dioxide by sunlight. On page 324 of this issue, Osthoff and colleagues 1 report ...
