Because ionic crystals contain ions which are arranged compactely by electrovalent force.in solutioon they become free ions because the solvent overcome their attractions so,they conduct electric current
In solid state the ions are packed very tightly, so ions are not free to move, therefore no conduction.
In the liquid phase (or dissolved in water), ions are able to move. That is what's necessary for electricity to flow in the body of an ionic compound. In the solid phase all those atoms are locked in position in the crystal. This is why the electrolysis of NaCl requires it to be molten (liquefied) first before it can conduct electricity.
It is called electrolysis.
No, liquid carbon dioxide is not an electrolyte. For a substance to conduct electricity, free moving electric charges must be present. Carbon dioxide is made of neutral CO2 molecules, thus there are no electric charges to conduct the electricity.
One can make liquid crystals quite easily. First one must get a container and fill it solution. Afterwards one must put salt in and stir until it is all dissolved. After that, one must heat the solution and continue adding salt. Then one must leave it for it to crystallize.
Magnetricity
because of the gravity or Magnetricity
Magnetricity.
because when the ions can move around freely, they can conduct electricity better

Yes, alcohol is a liquid and has delocalised electrons which can carry the electrical current. Edited: Seriously? Unless there are impurities in the alcohol that are electrolytes, alcohol will NOT conduct an electric current. Alcohols are considered as NON ELECTROLYTES, as they do not ionize and thus will not conduct a current. (Dr.J.)

In order to conduct electric current, salt has to be either dissolved in a liquid, or else melted in its own liquid form. A pile of dry salt out of the shaker won't do it.
Electric current does not need a liquid. It can pass in solids, liquids, gases, and even empty space. If it passes through a liquid, the liquid is called an electrolyte.
