WebE Mg2+/Mg = E ᶱ Mg2+/Mg – 0.0591 ... A negative value is that hydrogen gas is more stable than the reduced form of species. Here, the reduced form (Zn) is not stable. It is difficult to reduce Zn2+ to Zn. So, the reverse is more likely to happen. Zn would rather get oxidized to Zn2+ and H+ will get reduced. Web9. a) Draw a fully labelled diagram showing how you could measure the Evalue for the Mg2+/Mg system using a standard hydrogen electrode. Your diagram should show all the essential conditions for the experiment. (The Mg?*/Mg system means having magnesium metal in contact with Mg²+ions.)

WebThe Nernst equation is E is equal to E zero minus .0592 over n, times the log of Q. Well at equilibrium, at equilibrium E is equal to zero, so we plug that in. So we have zero is equal to the standard cell potential, E zero, minus .0592 over n, times the log of Q. But at equilibrium, remember, Q is equal to K.
