A3 resource to help students visualise what is happening during the electrolysis of four different aqueous solutions (*AQA REQUIRED PRACTICAL).

Splits the solutions into the anode and cathode. I tend to work through the first example on the visualiser in this order:
1 - Identify the four ions present in the solution
2 - Draw the two ions that would be attracted to the cathode in the cathode half, repeat for the anode.
3 - Use the rules printed at the top to then identify the product at each electrode.
4 - State the reason for each product (again using the rules at the top)

Students can then try the other three examples on their own.
