Question

Choose the electrochemical reaction from the following.

• A. Splitting water into hydrogen and oxygen by passing electricity
• B. Producing electricity in a lechianche cell
• C. Both of the above
• D. None of the above

Answer 1

Answer: (C)

Both of the above

Splitting water into hydrogen and oxygen by passing electricity and producing electricity in a lechianche cell are both electrochemical reactions.
Electrochemical reactions are either caused or accompanied by the passage of an electric current and involving in most cases the transfer of electrons between two substances.
Lechianche cell is primarily an electrochemical cell having a zinc cathode in contact with zinc chloride, ammonium chloride as the electrolyte, and a carbon anode in contact with a mixture of manganese dioxide and carbon powder.
