chemistry

• hydrogen is produced at 


  CATHODE
• chlorine is produced at 


  ANODE
• in aq solution less reactive elements are produced at 


  cathode and at anode you get oxygen
• oxidation is at the 


  negative electrode
• reduction is at the 


  positive electrode
• how does electrolysis work 


  breaks substance down using electricity
• what is a compound broken down by electrolysis called

  electrolyte
• negative ion is at


  anode
• positive ion is at 


  cathode
• when ions reach electrodes, they lose their 


  charge and become elements
• at exothermic reaction 


  heat is released
• at endothermic reaction 


  heat is taken in
• energy is c in chemical reaction

  conserved
• metals tend to 


  lose electrons from positive ions
• the greater the difference in reactivity the

  higher voltage produced by the cell
• hydrogen is one 


  alternative fuel
