ohh, shoot.

2Fe(III) + 3H2SO4 -> Fe2(SO4)3 +3H2 (g)

anonymous · Answer

why is it 2Fe(III)?

chmvijay · Answer

bcoz in right hand side it is 2 Fe are needed to balance the equation

anonymous · Answer

but on the right hand side isn't it Fe 2 and the left hand side, Fe(III)? So.. Fe 3?

chmvijay · Answer

no it remains the same !!!! check wheather in reactant it is in (II) state  bcoz sulphuric acid is good oxidising agent

chmvijay · Answer

it cannot oxidise Fe(III) further bcoz it is the maximum oxidation state iron havs

anonymous · Answer
