Question:

Identify the correct statement: Corrosion of iron can be minimized by forming a contact with another metal with a higher reduction potential; Corrosion of iron can be minimized by forming an impermeable barrier at its surface; Iron corrodes more rapidly in salt water because its electrochemical potential is higher; Iron corrodes in oxygen-free water

Corrosion of iron can be minimized by forming a contact with another metal with a higher reduction potential

Iron corrodes in oxygen-free water

Corrosion of iron can be minimized by forming an impermeable barrier at its surface

Iron corrodes more rapidly in salt water because its electrochemical potential is higher

Solution:

Corrosion of Iron can be minimized by forming an impermeable barrier at its surface. This can be removed by galvanizing or by using paints. Hence the option C is correct.
