KMno4 + (FeSo4(Nh4)2SO4 * 6H2O)=?

KClo3 + (FeSo4(Nh4)2SO4 * 6H2O)=?



i don't know how to solve this reaction pls help me if anybody know

For starters, if this is an aqueous reaction, try to break the reactants up into ions, like KMnO₄ could be written as K⁺ + MnO₄^-  Compounds won't necessarily break down into all atoms in a reaction.

I gotta be honest with you,  I don't recognize the compound FeSO₄(NH₄)₂SO₄ * 6H₂O.  (Notice I use proper capitalization and use this board's javascript sub & superscript -- it is important in this case)  I do know of ferric ammonium sulfate -- FeNH₄(SO₄)₂·12H₂O  could your compound be a typo?

Great!  Here's the ionization in aqueous medium, as a source of Fe²⁺ for titrations:
