Redox Reactions

Question

Give the points of difference between a redox reaction occurring in a beaker and in a cell ?

Answer

Redox reaction in a beaker(Direct redox reaction)  Redox reaction in an electrochemical cell (Indirect redox reaction)
1. Oxidation and reduction take place in the same vessel. 1. Oxidation and reduction take place in different vessels called half cells.
2. The transference of electrons occurs directly in the solution. 2. The transference of electrons takes place through connecting wires.
3. Energy is released in the form of heat. 3. Most of the energy is released in the form of electrical energy.
4. The cations accept the electrons at the surface of the cathode and metal formed gets deposited at the cathode. 4. The cations accept the electrons in solution and metal formed settles down as a precipitate.
5. Reaction quickly proceeds to completion. 5. The reaction does not proceed to completion.
