Question 5(c)(i)
[Maximum number: 3]
This question is about electricity and chemical reactions.
Spoons can be electroplated with silver.
Name the substances used as:
the anode (positive electrode)
the cathode (negative electrode)
the electrolyte.
CAIE IGCSE Chemistry 4.1.7 Metals are electroplated
Practise setting up electroplating by choosing the object, plating metal and electrolyte, then linking ions to the metal coating.
How this is tested
- choose the plating metal as the anode and the object to be plated as the cathode
- select an aqueous salt of the plating metal as the electrolyte,
- write or interpret the ion-electron equation for metal deposition,
