Answer:
This can he determined by
connecting the half cell carrying this reaction with a standard hydrogen
electrode acting as the other half cell. The reading in the voltmeter (+2.36 v)
gives the standard e.m.f. of the cell.
The direction of
flow of current is from S.H.E. to magnesium electrode which means oxidation
takes places at magnesium electrode (anode).
2.36 V = E2H
+ /H2 ?
2.36 V = 0 ?
