Potassium iodide is a halide.
The majority of these halide compounds are decomposed by water, with the formation of basic salts.
The atomic weight of silicon has been determined usually by analysis of the halide compounds or by conversion of the halides into silica.
of an alkaline halide.
When magnesium is heated in fluorine or chlorine or in the vapour of bromine or iodine there is a violent reaction, and the corresponding halide compounds are formed.
The most important of the halide salts is the chloride which, in the hydrated form, has the formula MgC1 2.6H 2 O.
