Why do liquid substances have the ability to permit the flow of current through them?

Question

Please explain well.

-extended thanks =)

Answer 1

First off, not all liquids allow current to flow through them, some are great insulators and allow no current flow.
The amount of free electrons in the liquid determines whether or not this can happen. it is all about the molecule makeup of the liquid. The more free electrons the better current flow capabilities. Mercury is one of the best conductors, De-ionized water is electrically neutral and does a poor job and is almost an insulator, hope this answer works.

Answer 2

Electrical current is the motion of charged particles. Liquid metals conduct because they have the same sort of mobile (charged) electrons that solid metals do. The atoms themselves have simply lost long range order (are loosely bound), and are mobile too. Liquids with dissolved ions conduct because some of the mobile atoms themselves are charged (aka ions). Liquids that do have dissolved ions (like distilled water) or cannot (like oil) are insulators.

Answer 3

they don't. only aqueous solutions do because there charged ions can carry the charge.
