Q30 / 90 · JEE Main 2016 (10 Apr Online) · Chemistry

Identify the correct statement:

  • A
    Corrosion of iron can be minimised by forming a contact with another metal with a higher reduction potential
  • B
    Iron corrodes in oxygen-free water
  • Correct answer
    C
    Corrosion of iron can be minimised by forming an impermeable barrier at its surface
  • D
    Iron corrodes more rapidly in salt water because its electrochemical potential is higher

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.

Hence, the correct answer is option: 'C'.
