That makes so much sense! I just checked the answer and you are correct but it also adds Fe2+ which is green /fe3+ which is yellow/orange any guesses as to why this happens? When oxidation occurs is everything just breaking down??


oxidation is loss of electrons, when a species looses electrons its charge increases by +1 per electron lost

for example, Fe2+(green) ---> F3+(orange) + e-

Another way I tend to spot oxidation is by loss of oxygen e.g. H2SO4 --> H2S

hope this helps, sorry if i stated the very obvious

nope, its correct to think of it like that


Yay!! Thanks for all your help

no worries mate, if you need any help on like rates/pH etc @ me in a thread. Hopefully, I'll have finished transition metals soon! And how are you finding f324?

Yeah I agree, but NMR is the biggest pain ever. And apparently they're not being friendly with f324 papers anymore, sucks to be us lmao.
