Question

Can AC be used for electrolysis?

Answer 1

The process of electrolysis:

• No, alternate current cannot be used for electrolysis. The process of electrolysis takes place when the ions move toward opposite electrodes.
• For electrolysis, the polarity of the electrode is maintained by DC current which supplies continuous current to the electrodes.
• If AC current is used the polarity of electrodes can continuously, which makes ionization of ions on the electrode difficult.

Thus, DC current is used for electrolysis.
