for anyone confused about electrode potential (sign) see its simple just use concept instead of formulas see if u reverse the equation OBVIOUSLY sign of the electrode potential changes if you removing an electron instead of adding Will electrode potential remain same?? no
-so first see which half cell reaction has a higher potential that will gaining electron (reduction) keep its question forward with the same +potential
-now reverse the other cell equation as if one is reducing its ganing electron where does the electron come from? from the other cell which is oxidising so reverse the sign for this other question as ur reversing it equation (oxiding)
now add the 2 values as one is reducing the other is oxidising we have to see which one is more like potential provided by the oxidising of that electron is enough for the reducing process to accept that electron in order that reaction happens

Wa alykumussalam.
I dare you write ur name in 2 secs :ROFLMAO:
jk:p
Thanks a lot though:) Jazak Allahu Khair!!!:D

Brother... but there's no denying that there's another way as well right? Have you read the previous few pages? I dunno, it was proven that both ways of changing the sign and not changing the sign exist.. is that right?

brother, i'm assuming ur using the same book as mine cz ur in Jeddah, can u please answer qnother question?
Look at page 278 of our txtbk, fig 19.12? Can u please tell me how to figure out the half equation of the half cell on the left hand side?
btw, @everyone who has the same txtbk:)

its simple as hydrogen electrode potential=o so electrode potential obtained on the voltmeter= electrode potential of the platinum

honestly speaking u can use both ways but that sort of memorizing the ways those are ways which people memorize but the main deal is to understand what u are studying that why i explained the real thing going on but u can use any method which your most comfortable with.
the main thing in these question is PRACTICE the more u understand

Walaikum Assalam

I don't have the orange text book, but i have the fat golden textbook
But i know a friend who has the orange one, and orange one is good for definitions, but the golden one is good for explanations... :p

And im not a brother... :p
