@diamondboy B right?

jfraser · Answer

From the reaction you gave, which half-reaction is the reduction half?

vera_ewing · Answer

i'm not sure...

diamondboy · Answer

is it Zn2+ ----> Zn + e-; I am not sure?

vera_ewing · Answer

the answer is B right? @JFraser

jfraser · Answer

reduction is the $gain$ of electrons. Which reactant gains electrons?

jfraser · Answer

it's the $$Fe^{+3} + 1e^{-1} \rightarrow Fe^{+2}$$
