Resource summary

Electrolysis
1 What is electrolysis?
1.1 Electrolysis is the breaking down of a compound using electrical energy
1.2 The electricity used comes from a direct current source.
1.2.1 A battery
1.2.2 Thermocouples
1.2.3 Solar cells
1.3 It requires a liquid to conduct the electricity, called the electrolyte
1.3.1 The electricity is applied to the electrolyte by two electrodes
1.3.1.1 The electrode contains the compound, which is broken down into its component parts
1.3.1.1.1 The component parts are released as atoms or molecules
1.3.1.1.1.1 Often as a gas
1.4 The main components required for electrolysis are;
1.4.1 An electrolyte
1.4.1.1 A substance containing free ions, which are the carriers of the electric current
1.4.1.2 If the ions are not mobile, electrolysis cannot take place
1.4.2 A direct current supply
1.4.2.1 Provides the necessary energy to create or discharge the ions in the electrode.
1.4.3 Two electrodes
1.4.3.1 An electrical conductor which provides the physical interference between the electrical circuit
2 Electrolysis; Hydrochloric Acid
2.1 The electrolyte is a dilute solution of hydrochloric acid
2.2 Applying a direct current to the electrolyte causes the hydrochloric acid to decompose into its two component parts
2.2.1 Hydrogen gas
2.2.2 Chlorine gas
2.3 The gases bubble through the solution and can be collected at the electrodes.
