- 1Electrolysis is...Chemical decomposition produced by passing an electric current through a liquid or solution containing ions.
- 2Electrolyte is...An ionic substance with freely moving ions. Electrolytes conduct electricity.
- 3A cation is...A positively charged ion
- 4An anion is...A negatively charged ion
- 5The steps to electrolysis are...Electrolysis uses electricity to break down an electrolyte. Two electrodes (usually a carbon or a metal) are connected to a d.c. current and placed in the electrolyte.
- 6The steps of electrolysis are...Two electrodes (usually a carbon or a metal) are connected to a d.c. current and placed in the electrolyte.
- 7The steps of electrolysis are...The ions migrate towards the electrode with the opposite charge.
- 8The positive electrode is called...The anode
- 9The negative electrode is called...The cathode
- 10Cations collect at the...Cathode
- 11Anions collect at the...Anode
