Electrolysis
When an electric current is made to pass through some liquid, the liquids dissociate into their component parts. This process is called ‘electrolysis’.
Electrolysis is therefore defined as the process of decomposing certain liquids and solutions into their component parts by the passage of electricity through them.
Terms Used in Electrolysis
- Electrolyte: The liquid being broken down by the passage of electricity.
- Electrode: Metal plates conductors in contact with the electrolyte, through which current enters and leaves the electrolyte. The positive electrode is the anode, while the negative electrode is the cathode.
- Voltameter: The vessel containing the electrolyte and the electrodes. Electrolysis takes place in the voltameter.
Electrolysis of Acidified Water
When current passes the such water, it is broken down into hydrogen ion and hydroxyl ion.
