No it doesn't .
Yes
Hydrochloric acid can conduct electricty.
yes, as all it's constituent substances can also conduct electricity
Not usually. With a sufficiently high voltage, however, nitrogen can be caused to ionize and then can conduct electricity.
Potassium bromide can only conduct electricity when it is in liquid form.
Yes, particularly acidic ones like citrus.
if something has delocalised electrons it has the possibilty to conduct electricty
metal plus energy
yes gold is a good conducter of heat and electricity
When CaCl2 is placed in water, CaCl2 dissociates, Ca+ and Cl- and ions conduct electricty.
Most metals are good conductor's of electricity.
