1. Explain the function of a galvanic cell.
Answer:
A galvanic cell is an electrochemical cell used to supply electrical current by making the transfer of electrons through a redox reaction. During redox reactions, the galvanic cell converts chemical energy into electrical energy by transferring energy between the electrons.
2. How does an electrolytic cell work?
Answer:
An electrolytic cell converts electrical energy into chemical energy. In this cell, the redox reaction is not spontaneous, and electrical energy is required to initiate the reaction.
3. What is a half-cell or electrode?
Answer:
It is a metal used to conduct electrons in a cell.
4. What is cell potential?
Answer:
In a cell, the potential difference between the two electrodes is called cell potential.
5. What is the electrochemical series? What is the potential of S.H.E?
Answer:
Electrochemical series: The various elements are arranged in the increasing order of standard reduction potential.
