The oxidation half and the reduction half of a voltaic cell are made of the same electrodes and the same electrolyte. The concentration of electrolyte is different in each compartment.
A voltaic cell is constructed with an Ag/Ag+ half-cell and a Pb/Pb2+ half-cell. Measurement shows that the silver electrode is positive. Write balanced half-reactions and the overall spontaneous reaction.
A reactor is used to decompose toxic H2S gas (that was removed from natural and petroleum gas). The reaction is given as:H2S (v) = 2H2 (v) + S2 (l)
