Conditions necessary for electrolysis
Chemistry
ScanSolve AI Answer
The conditions necessary for electrolysis to occur are:
- Presence of an electrolyte: This is a substance that contains free-moving ions, either in a molten state or dissolved in a solvent (like water). These ions carry the electric charge.
- Presence of electrodes: These are electrical conductors (usually metal or graphite) that are dipped into the electrolyte. They provide the surface for the redox reactions to take place.
- Application of a direct current (DC) power supply: An external power source is needed to drive the non-spontaneous chemical reactions by forcing electrons to flow through the external circuit and ions to move towards the electrodes.
