Worksheet: Electrolysis

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

Q1:

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

Q2:

Where does the reduction reaction occur?

  • AWithin the potentiometer
  • BAt the anode
  • CWithin the salt bridge
  • DAt the cathode
  • EWithin the bulk solution

Q3:

Where does the oxidation reaction occur?

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

Q4:
