how many moles of chlorine are required to oxidize 3 moles of Fe^2+ according to the equation given ? fs^2+ + Cl2--------> Fe^3+ + Cl^-​

The first is a potentiometric flow injection method in which a redox couple such as Fe(III)-Fe(II), Fe ( C N ) 6 3 ... R e d 1 ⟶ R e d 2 + m O x 1 ( 1 ) where m is the number of moles of Red1 required to reduce 1 mole of O
