At which electrode does oxidation occur in a voltaic cell?

a: anode only

b: cathode only

c: either anode or cathode, depending on the metal

! : d

Option (A) is the correct answer.

Explanation:

An electrochemical cell that utilizes chemical reactions in order to produce electrical energy is known as a voltaic cell.

In a voltaic cell, cathode is a positively charged electrodes where gain of electrons take place and hence, reduction occurs.

Whereas anode is a negatively charged electrode where loss of electrons take place and hence, oxidation occurs.

Thus, we can conclude that at anode electrode oxidation occurs in a voltaic cell.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
