The statements which are true about electrolysis are;
- Electrolysis is described by two half-reactions.
- Electrolysis results in commercially valuable products.
- Electrolysis involves the transfer of electrons.
The true facts about electrolysis are as explained;
- Electrolysis is described by two half-reactions. These half reaction are the oxidation half-reaction and reduction half-reaction
- Electrolysis results in commercially valuable products. This is evident in electroplating when valuable metals are use to plate one's of less value.
- Electrolysis involves the transfer of electrons. Each half reaction is characterized by the loss or gain of electrons.
- Oxidation results in the loss of electrons.
The false statements are;
- Electrolysis requires an acid to be present. This is false because the presence of an acid is not mandatory during electrolysis.
- Electrolysis is not an industrial process. The statement above is false because industrial purification of many metals require electrolysis.
- Reduction results in the loss of electrons. Contrarily, reduction is characterized by a gain of electrons.
