Identify the correct statement:

Identify the correct statement:

Options

  1. ACorrosion of iron can be minimised by forming a contact with another metal with a higher reduction potential
  2. BIron corrodes in oxygen-free water
  3. CCorrosion of iron can be minimised by forming an impermeable barrier at its surface
  4. DIron corrodes more rapidly in salt water because its electrochemical potential is higher

Correct answer

C. Corrosion of iron can be minimised by forming an impermeable barrier at its surface

Step-by-step solution

Corrosion of iron can be minimised by forming a contact with another metal with a lower reduction potential. Corrosion of iron can be minimised by forming an impermeable barrier at its surface.
