Best ResponseYou've already chosen the best response.0Ok, reduction reaction is when any species gains electron. The reaction which you have been given can be written as follows: \(\sf Mg + Cu^{+2}+SO4^{2} \rightarrow Mg^{+2}+SO4^{2} + Cu\)

Best ResponseYou've already chosen the best response.0Which one has =+ve charge on the left hand side but is neutral on right hand side?

Best ResponseYou've already chosen the best response.0Yes, so we can say that the reduction half is : \(\sf Cu^{2+} +2e^ \rightarrow Cu\) Notice since it had 2+ charge before and neutral after that's why it must have gained 2 electrons.
