Ionic compounds dissolved in water are better conductors of electricity than when they are in solid form. Why is this true?

In their bonded, solid states, molecules like salt don't conduct electricity. But when they're dissociated in a solution or through melting, they can carry a current. This is because electrons can't move freely through water (in the same way they do in a conductive wire), but ions can move freely
