Questions and Answers
What are the two terminals connected to the electrodes?
What are the two terminals connected to the electrodes?
The positive terminal and the negative terminal are connected to the electrodes.
What is the electrode called that is connected to the negative terminal?
What is the electrode called that is connected to the negative terminal?
The electrode connected to the negative terminal is called the cathode.
What happens when an electric current is applied from the positively charged terminal?
What happens when an electric current is applied from the positively charged terminal?
The applied electric current forces the negatively charged ions towards the anode. When an electric current is applied, the positively charged ions move towards the cathode.
Study Notes
Electrolytic Cell Working
- Electrodes connected to battery terminals
- Positive terminal is the anode
- Negative terminal is the cathode
- Anions (negatively charged ions) move towards the anode
- Anions lose electrons at the anode, undergoing oxidation
- Cations (positively charged ions) move towards the cathode
- Cations gain electrons at the cathode, undergoing reduction
- Chemical reactions occur at the electrodes
- Example: 2NaCl(l) → 2Na(l) + Cl₂(g)
