finding top of your series

Postby bellaha4F » Fri Feb 28, 2020 1:21 pm

i'm a little confused on how to find the top of your series in a redox reaction (ie the strongest oxidizing agent in reduction). can someone please explain, thank you!

I think the strongest oxidizing agent is the one that has the most positive E value. So, for example Ag+ + e- -> Ag (E=.80V) and AgBr + e- -> Ag + Br-(E= .07V). In this case, the first reaction is the better oxidizing agent

Yes, the E value corresponds to the element with the highest oxidation.

In an electrochemical series, the E values are given in terms of the reduction potentials. The strongest oxidizing agent will be the one with the greatest (most positive) reduction potential since it will be the one that is more likely to be reduced. (Remember that the oxidizing agent causes oxidation of another molecule, so it itself is reduced)
