Question

3
Lower is pH, corrosion is,
A
Greater
B
Lower
C
Constant
D
None of above​

Answer 1

Answer:

Corrosion is greater as the ph scale shows how strong/weak an acid or a base is.

Answer 2

The lower is the pH of any solution, the greater is the rate of corrosion of the solution.

Option(a) Greater.

• Corrosion is an irreversible reaction.
• The process in which a metal reacts with the surroundings resulting in the consumption of the material is known as corrosion.
• The pH is the measure of the acidic or basic nature of any solution.
• Lowering the pH increases the rate of corrosion.
• There is the development of a passivation layer in moderately alkaline (high pH) solutions on the metals, which lowers the corrosion rate as compared to acidic (low pH) solutions.
• The layer on metal provides a measure of immunity to further corrosion.
• Hence, the lower the pH is the greater will be the rate of corrosion.
