Calculate the reduction potential for the following half cells at 25^@C Mg|Mg^(2+) (1 times 10^-4 M), E_(Mg,Mg^(2+))^@=+2.36V

Answer»

SOLUTION :`Mg^(2+)+2e LEFTRIGHTARROW Mg`(REDUCTION)
`E_(Mg^(2+),Mg=E_(Mg^(2+),Mg))^@+0.0591/2log(1 times 10^-4)`.......[see example]
`=-2.36 - (4 times 0.0591)/2=-2.4782 V`
