Answer:
Dear tirumalasandeep@yahoo.com
Thanks for asking us a question in Ask the Expert section of TopperLearning.com.
From the provided oxidation half reactions,
(a) Fe2+ solutions are not stable in air, as it gets oxidised to Fe3+ when exposed to air.
(b) Fe nails can prevent oxidation of Fe2+ to Fe3+ by air because the oxidation potential of Fe to Fe2+ is high. So iron nails in which Fe is present in Fe form gets oxidised before Fe2+ present in the solution when exposed to air.
(c) Oxidation of Fe by air to Fe2+ is called corrosion of Fe.
So all the options are correct.
Regards
Topperlearning Team.
