SSC CGL Previous Year Questions: General Science - 2 - Question 16

Rusting is __________.       (SSC CGL 2017)

Detailed Solution for SSC CGL Previous Year Questions: General Science - 2 - Question 16

Rusting of iron is an example of a Redox reaction.

  • Redox reaction = Oxidation-Reduction reaction. In this reaction, an oxidation number of a molecule, atom, or ion changes either by gaining or losing an electron. 
  • The substance which gets reduced in a chemical reaction is known as the oxidizing agent and a substance that gets oxidized in a chemical reaction is known as the reducing agent.
  • Rusting is the corrosion of iron. Iron forms red-brown hydrated metal oxide (rust) in the presence of water and air. 
  • Iron is oxidized to Fe2+ and oxygen is reduced to water. Rust keeps on forming due to the subsequent oxidation of Fe2+ by atmospheric oxygen.
  • Therefore we can say that rusting is a redox reaction because oxygen acts as an oxidising agent and iron acts as a reducing agent.
