Question

During the electrochemical corrosion in acidic environment
A. H2 evolution
B. CO2 absoption occurs
C. O2 evolution occurs
D. H2 absorption occurs

Answer 1

Answer:

friend the answer is CO2 absorption occurs hope this answer had helped you

Answer 2

The correct answer is (a) H2 evolution.

• Electrochemical corrosion of metals happens when electrons from particles at the outer layer of the metal are moved to a reasonable electron acceptor or depolarizer.
• Water should be available to fill in as a mechanism for the vehicle of particles.
• The most widely recognized depolarizers are oxygen, acids, and the cations of less dynamic metals.
• This is additionally called Galvanic cell corrosion.

This sort of electrochemical corrosion happens in two unique ways.

(i) With the evolution of hydrogen

(ii) With the absorption of oxygen.
