elec cell

PLz discuss this prob??? At pH=2, EÂ°_quinhydrone=1.3 , then E_quinhydrone=????

a)1.36V b) 1.3 c)1.42 d)1.2

its a rqst....plz solve this....

QUIN HYDRONE ELECTRODE :-

http://en.wikipedia.org/wiki/Quinhydrone_electrode

E quinhydrone = EÂ° quinhydrone - 0.0591 pH

Nice one tushar...and I was thinking of nernst equation!

but that doesnot give the ans

ans is (c)
pH = {E_CELL - EÂ°_REF } / 0.0591
hence E_CELL = 4.2

thanks debo..i had compltely forgoten abt ths exp...
