- Assign the anode and cathode and identify oxidation and reduction from the stated electrode reactions in voltaic or electrolytic cells.
- Label a cell diagram with electrode species, electron-flow direction and the relevant electrode processes.
- Distinguish electrode polarity in voltaic versus electrolytic cells while retaining oxidation at the anode and reduction at the cathode.
IB Chemistry SL 3.2.5 Electrodes in Electrochemical Cells Questions question 1
Iron(II) sulfide can be produced by heating powdered iron and sulfur together.
A student hypothesised that iron(II) sulfide is ionic and therefore can be converted back to iron and sulfur by electrolysis of the molten salt, using inert electrodes.
Annotate the electrolytic cell with the terms anode and cathode, and show the direction of ion movement.
