Question

What is the difference between ferric and ferrous?

Answer 1

Fe+2 is ferrous ion and Fe+3 is ferric ion .These are different forms of iron as an cation.Every metal has a tendency to lose electrons very easily.Iron being a metal also does the same . After losing electron metal gains a positive charge .It depends on the type of metal how much electrons it can lose. Like ,Alkali metals generally lose 1 electron,alkaline earth metals 2 electrons.
Fe(iron) is a d block element, i.e. they can show variable oxidation state
It can either lose 2 electrons or 3 electrons,giving rise to ferrous and ferric.
Hope this helps.
