     • When the solid ionic compound is heated to its melting point, the substance becomes molten. The lattice is broken down and the ions are released from their fixed positions. As the ions are now able to move, the molten ionic compound will conduct electricity and the process of electrolysis can be used.

   What is electrolysis in chemistry?

   • What is electrolysis? Electrolysis is breaking up an ionic compound (either molten or in solution) into simpler substances by using an electric current. A flow of electricity through a metal or carbon is simply a flow of electrons.

   Why does an electrolyte have to be molten?

   • An electrolyte is a compound which undergoes electrolysis. The reason that an electrolyte has to be molten or in solution is that the current is carried through the electrolyte by the movement of ions - not electrons. In a solid, those ions can't move. It also follows, of course, that an electrolyte must contain ions.

   What are the basic terms and ideas in electrolysis?

   • This page introduces the basic terms and ideas in electrolysis by looking at the electrolysis of molten compounds. Most people will have met all this in chemistry courses for 14 - 16 year olds. The flow of electricity through a metal or carbon is due to the movement of electrons. The metal or carbon isn't chemically changed in the process.

   Can electrolysis happen if a compound is molten?

   • Electrolysis can't happen unless the ions can move to the electrodes. We are starting with the simpler case - where the electrolyte is molten. One of the common compounds to electrolyse molten is lead (II) bromide - partly because the products are easily visible, and partly because its melting point isn't too high.

   What happens if sodium chloride is melted before electrolysis?

   • Therefore, the electrolysis of an aqueous sodium chloride solution yields sodium hydroxide, hydrogen, and chlorine. 3. Molten Sodium Chloride (NaCl) Sodium chloride is melted to its molten state above 800 ˚C before performing electrolysis.

   How does electrolysis extract metals?

   • Electrolysis can be used to extract the metal from the leachate solution produced during the process. Learn more on extracting metals using electrolysis in this podcast. Listen to the full series on BBC Sounds. It is expensive, largely because of the amount of electricity required in the extraction process.
