level questions: Galvanic cells
| Question | Answer |
|---|---|
| Define a cathode | The electrode where reduction (gain of electrons) occurs during an electrochemical reaction. |
| Define an anode | The electrode where oxidation occurs during an electrochemical reaction, attracting positively charged ions or electrons. |
| Explain how two half-cells can be connected by a salt bridge to create a voltaic cell. | Two half-cells can be connected by a salt bridge to create a voltaic cell, allowing the flow of ions between the half-cells to maintain charge neutrality and facilitate the redox reactions that generate electrical energy. |
| How to determine the strength of oxidising and reducing agents? | Comparing their standard electrode potentials. |
