Edexcel IAL Chemistry A2 16.6 Core Practical 12 electrochemical cells
For practical cell questions, label both half-cells, show the salt bridge and voltmeter, then explain how soaked filter paper lets ions move.
How this is tested
- Draw a standard cell with labelled electrodes, solutions, salt bridge and voltmeter.
- Describe a salt bridge as filter paper soaked in KNO3 or another suitable electrolyte.
- Correct apparatus errors such as a power supply, wrong electrode or missing salt bridge.
