Question

Why does sodium chloride conduct electricity when it is molten?

Answer 1

$\huge\mathbb\red{HEY \:THERE !}$

In order to conduct electricity a substance must have charge particles, such as electrons and ions, that are free to move freely through it. However in the molten state, ions in ionic compounds are free to flow and therefore molten sodium chloride can conduct electricity.

Answer 2

in molten state ions in ionic compound are free to flow thats why it conduct electricity in molten state
