Question

Difference between chemical corrosion and electrochemical corrosion

Answer 1

Hey, here are a few differences between the two

Chemical Corrosion                                          Electrochemical Corrosion

- Mostly in dry situations                                   - In the presence of
                                                                           electrolytes or other moisture
- Homogeneity or heterogeneity                        - Takes place only on
of surface doesn't matter                                   heterogeneous surfaces
- Corrosion happens uniformly                          - The corrosion is not uniform
- It is a relatively slow process                          - It is a relatively fast process

Answer 2

Solution:-

》chemical corrosion:-
It occurs in wet conditions such as presence of electrolyte or moisture. It takes place by direct chemical attack of atmospheric gases such as O2, CO2, Cl2, 

》Electrochemical corrosion:-
☆ H2S, SO2. It takes
place by electrochemicalattack of corrosive environment on the surface of metal.☆
