Question

The charge carriers in metallic conductors and in electrolytes are respectively:

• A. both ions
  
• B. both electrons
• C. electrons and ions
• D. ions and electrons

Answer 1

The correct option is C electrons and ions

Electrolysis is the passing of a direct electric current through an ionic substance that is either molten or dissolved in a suitable solvent, producing chemical reactions at the electrodes and separation of materials.

In metallic conductors, electrons carry the current and the material is unaffected by this flow for small currents.
