Questions and Answers

What branch of chemistry is Electrochemistry?

Electrochemistry is the branch of chemistry in which the relationship between chemical energy and electrical energy and their transformation are studied.

What is an electrochemical cell?

An electrochemical cell is a device in which the chemical energy of the redox reaction is converted into electrical energy.

Electrolytic cells convert electrical energy into chemical energy.

True

What is electrode potential?

When a metallic is dipped in a solution of its ions, then a potential is developed b/w the plate and the soln so the plate acquires the positive and (-)ve charge this develop the potential which is known as electrode potential (E). Signup and view all the answers

What is standard electrode potential?

If the concentration of all the ions used in a half cell is unity, temperature is 25°C and pressure is in atm, then the measured electrode potential is called standard electrode potential (S.E.P) Signup and view all the answers

Study Notes

Electrochemistry

Electrochemistry is the branch of chemistry studying the relationship between chemical and electrical energy, and their transformations.
Electrochemical cells convert chemical energy into electrical energy, while electrolytic cells do the reverse.
An electrochemical cell is a device that converts chemical energy from a redox reaction into electrical energy.
Electrode potential (E) is the potential difference developed between an electrode and the electrolyte solution when a metal is dipped into its own ion solution.
Electrode potential depends on the nature of the electrode, temperature, and the concentration of metal ions in the solution.
Standard electrode potential (S.E.P) or (E°) is the electrode potential measured under standard conditions (25°C, 1 atm pressure, and unit concentration of ions).
