Question

5 Fe2+ + MnO4- + 8 H+ ---> 5 Fe3+ + Mn2+ + 4 H2O

Answer 1

In the equation above

H+ ions are reduced

Fe2+ ions are oxidized

H+ is the oxidizing agent

MnO4- is the reducing agent

Answer 2

Leo the lion says Gerrr

LEO GER

Lose electrons Oxidation Gain Electrons Reduction

Answer 3

I can't say I have heard of that

Answer 4

It is a good way of remembering of what oxidation and reduction is,

Also note,
A reducing agent gets oxidized
A oxidizing agent gets reduced

Answer 5

Which is kind of confusing

Answer 6

Not bad since it's just the opposite

Answer 7

Would it be that Fe2+ ions are oxidized?

Answer 8

what is the question exactly? Does it just give you one to select?

Answer 9

Just the equation and then the multiple choice part where you choose which answer fits the equation

Answer 10

I believe you are correct, pretty tired though, just go through each choice individually and evaluate based on what I told you.

Or you could write out their half reactions which would let you know what is going on.

In regards to hydrogen it keeps its oxidation state of +1, oxygen is -2


Iron increases in an oxidation state mean that it got oxidized meaning it is a reducing agent.

MnO4- as a reducing agent, I would assume it is an oxidating agent it takes up some of irons electrons,

Magnesium goes from a +8 to a +2 oxidation state

Answer 11

Sorry manganese

Answer 12

really tired

Answer 13

it's fine, thanks for all the help though! it's 2:05 am here :p

Answer 14

You know how to assign oxidation state just use that tool to figure out what is being reduced and what is being oxidized. Have a good night, yeah it is that time here as well, you should sleep as well

Answer 15

Best time to study is before you go to bed though

Answer 16

mind is decently active and need to find some work anyways

Answer 17

I should really be doing my own work and not on this site ha anyways gone now bye and good luck read about the trends though seriously

Answer 18

some are less important though, atomic radious, electron affinity are pretty important maybe ionization energy. Melting point etc not that important
