IB Chemistry 3.2.6 Primary (voltaic) cells Questions
Learn to set up and interpret voltaic cells by labelling half-cells, salt bridges and voltmeters, then predicting electron flow and electrode changes.
How this is tested
- draw and label a voltaic cell: two half-cells, electrodes, salt bridge, wires, and voltmeter or bulb
- use reactivity or E° data to deduce electron flow, ion movement, and which electrode gains or loses mass
- distinguish primary, secondary, and electrolytic cells by rechargeability and whether electricity is produced
