Weba) Draw a fully labelled diagram showing how you could measure the E0 value for the Mg2+/Mg system using a standard hydrogen electrode. Your diagram should show all … 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.

WebIf we are reducing copper 2+ to solid copper, the standard reduction potential is +.34 volts. If we are reducing zinc 2+ to solid zinc, the standard reduction potential turns out to be -.76 volts. The more positive value, the more likely the substance is to be reduced, so obviously +.34 is more positive than -.76. WebScribd is the world's largest social reading and publishing site.
