A voltaic cell consists of a standard hydrogen electrode and a second half-cell in which a magnesium electrode is immersed in a 1.00 M solution of Mg2+ ions. Calculate Ecell given that the standard reduction potential for the magnesium half-reaction is -2.37 V.

The correct answer is "+2.37 V".

Explanation:

Given that,

Concentration of

= 1.00 M

,

= -2.37 V

,

= 0.00V

When S.H.E as well as anode act as cathode, then

⇒

By putting the values, we get

⇒            

⇒                

i think it is true since you can test the answer and can use observations to complete it.
