[Chemistry Form 4] Conductive

• Conductors are substances that can conduct electricity in a solid or molten state, and are not chemically changed.
  
  
• Electrolytes are substances that can conduct electricity either in a molten state or an aqueous solution, as well as undergo chemical changes at the same time.
  
  
• Non-electrolytes are substances that cannot conduct electricity either in a molten state or an aqueous solution.
  
  
• Electrolysis is the decomposition of a chemical compound into its constituent elements when an electric current passes through an electrolyte.
  
  
• An electrolytic cell ia a device that uses electrical energy to generate chemical reactions.
  
  
• Electrodes are conductors that transmit electricity through the electrolyte during electrolysis.
  
  
• Cathode is the electrode that is connected to the negative terminal of a battery.
  
  
• Anode is the electrode through which the electrons leave the electrolyte and move to the external circuit.
  
  
• Molten compounds or aqueous solutions can conduct electricity due to the presence of free moving ions.
  
  
• During electrolysis, cations move towards the cathode, where they will be discharged by accepting electrons, whereas anions move towards the anode, where they will be discharged by donating electrons.
  
  
• A voltaic or galvanic cell is a device that converts chemical energy into electrical energy.
