英语翻译
ionic substances conduct electricity when molten or in aqueous solution-they are electrolytes.Since the ions have been freed from their fixed positionin the crystal they are able to move.Thus an electric current can pass through when a voltage is applied between two electodes dipped into the ionic melt or solution.
如果有打错字的地方,请见谅.

答案

离子物质在熔化时或者在水溶液中导电－它们是电解质.因为这些离子被从它们在晶体中的固定位置释放出来所以它们可以移动.因此当一定电压被施加在两个浸在离子熔化物或溶液中的电极时电流可以通过.
