Electrolytic Conductance

Q:
Do different electrolytes work better at carrying an electric charge? I know Na+Cl or salt works in water, but what are some others?
Thanks

A:
Yes, different ions conduct electricity different amounts. For example
H+ ion has much higher mobility (a measure of how fast it moves in an
electric field) than does Na+ or other similar salt ions. Thus a given
number of molar concentration of HCl (hydrochloric acid) will conduct
electricity better than the same molarity of NaCl. Divalent (doubly
charged) ions (like Mg++) general conduct better than monovalent ions
(like Na+) because they carry twice as much electric charge. You can
find standard tables of mobilities of common ions in aqueous solution.
