The Alkali Metals - Properties of Compounds.
All alkali
metal compounds with
non-metals are white solids
which have ionic giant structures.
These compounds are all soluble in water
and form colourless
solutions.
1) Chlorides.
All the chlorides are ionic salts.
Electrolysis of
the molten
chloride will give
the metal at the cathode (negative
electrode)
and chlorine at the anode (positive
electrode)
Electrolysis of the chloride salt in
water will give
hydrogen at the cathode and chlorine
at the anode.
See the electrolysis of sodium chloride in
water.
2) Oxides and Hydroxides.
The oxides and hydroxides are alkaline in solution.
The oxides react with water to
form alkaline
hydroxides.
The alkaline hydroxide may be neutralised by an
acid to form a salt + water.
