Indicate whether the following statements are true or false

1. In electronic conductors, the current is conducted by electrons. 
2. Electrolysis of acidified water produces 2 parts of O₂ and 1 part of H₂ by volume. 
3. lons are charged atoms or groups of atoms. 
4. During electrolysis of aqueous CuSO₄ solution using cu-electrodes, the weight of Cu-anode increases. 
5. During electrolysis chemical reaction takes place at the anode is reduction.

Answer

1. True
2. False; Electrolysis of acidified water produces 2 parts of H₂ and 1 part of O₂ by volume.
3. True
4. False; The weight of the Cu-cathode increases
5. False; Oxidation occurs at the anode.
