内容記述 | It becomes clear that the potentials of a Daniell cell do not occur due to electrons which come from oxidation reaction Zn→Zn2++2e- and reduction one Cu2+2e-→Cu, but due to electrons which come from the following oxidation reaction M (Zn, Cu) +nH+→Mn++n/2・H2+ne-. Therefore a Daniel cell should be expressed by Cu| H+(xm)||H+(xm)|Zn istead of Cu|Cu2+(xm)|Zn. This shows that a voltaic cell Cu|H+(xm)|Zn is same as a Daniell cell Cu|H+(xm)||H+(xm)|Zn, because a salt bridge is only used as circuit of electrons. Accordingly a water cell Cu| H2O| Zn is possible, bebause a water cell is the voltaic cell with solution of 10-7m H+. The equation pH=△E/0.059-1, where △E is the potential of the cell Pt|H|H+(1m)||H+(xm)|H|Pt and pH=-log H+(xm), is theoretically obtained, based upon the above-mentioned mechanism of potential occurrence. | |||||
