A hydrogen electrode placed in a buffer solution of CH_3COONa and acetic acid in the ratio.sx:y and y:x has electrode potential values E_1 volt and E_2 volt respetively at 25^@C thepKa values of acetic acid is (E_1 and _2 are oxidation potential ):

Answer»

`(E_1+E_2)//(0.118)`
`(E_2+E_1)/(0.118)0`
`-(E_1 +E_2)//(0.118)`
`(E_1+E_2)//(0.118)0`
