so i've got 6 equations on the paper in front of me. i'm supposed to "indicate the element that has been oxidized and the one that has been reduced. Also label the oxidation state of each before and after the process" but i didn't pay attention when he was going over it, therefore, i have no idea what to do -.- if someone could explain it to me, that'd be great. first question is 2Na+FeCl(subscript2) > 2NaCl+Fe

god i hated redox. Na got oxidized, i think and Fe was reduced.

[quote] screech1941 : god i hated redox. Na got oxidized, i think and Fe was reduced. [/quote] which is because sodium gained an ion and iron lost ions? yea i'm clueless...need some confirmation lol

what grade are you in? im in gr11 and i havent learned wat the heck oxidation is edit: unless it means ...type of chemical reactions

Sodium lost an electron, because in its solid state ( which is what im assuming it is), it has 0 charge, but in NaCl, it has +1 "charge", even though its really a pseudo charge. Fe has 2+ charge in FeCl2 and a 0 charge as Fe which means it gained electrons, which means it got reduced. @above- yeah redox are a type of reaction, similar to displacement, acid/base, and combustion reaction.

An Ox = Anion Oxidation Red Cat = Reduction Cation Atoms always have a charge of 0 unless indicated. Therefore, Na by itself has a charge of 0. When combined with Cl, Na takes on a charge of +1 to balance Cl's -1 charge, forming a neutral compound NaCl. Because Na lost an electron to take on that positive charge, Na is oxidized, and it can be called the reducing agent since it reduces Cl. Fe is +1 to balance Cl in the compound FeCl. Fe is reduced to Fe with 0 charge because Fe stands by itself.

Look at the charges... If an element's charge is higher in the reactants than it is in the products, it was oxidized. If vice versa, it was reduced. D'oh!

wait what is the 2nd part of the question asking? i'm guessing that corresponds to the first part i need to stop screwing around in that class D: at least when he says it's something important lol

Oxidation state is basically put 0 on the top right corner of Na and Fe, -1 above Cl, and +1 above Fe and Na in this case.

OIL-Oxidation Is Loss (of electrons) RIG-Reduction Is Gain (of elctrons) OILRIG Now, half reactions can be very easy, I found that in Chemistry I, the user 'bananaiscool' on youtube, has very good tutorials. Helped me get a 100 on my Redox quiz, and a 97 on my Redox test.
