Worksheet: Electrolysis

In this worksheet, we will practice describing the components of electrolytic cells and predicting the products of electrolysis using the reactivity series.


What is the purpose of the salt bridge in a galvanic (voltaic) cell?

  • ATo provide a site for oxidative reduction
  • BTo provide free electrons for redox processes
  • CTo serve as a working electrode
  • DTo complete the electrochemical circuit
  • ETo serve as a reference electrode


Where does the reduction reaction occur?

  • AWithin the potentiometer

  • CWithin the salt bridge
  • DAt the cathode
  • EWithin the bulk solution


Where does the oxidation reaction occur?

  • AWithin the salt bridge
  • BWithin the potentiometer
  • C At the cathode
  • DAt the anode
  • EWithin the bulk solution
