A galvanic cell consists of a Cd(_s_)|Cd2+(_aq_) half-cell and a Zn(_s_)|Zn2+(_aq_) half-cell connected by a salt bridge. Reduction occurs in the cadmium half-cell. The cell can be represented in standard notation as Cd(_s_)|Cd2+(_aq_) || Zn(_s_)|Zn2+(_aq_ Zn(_s_)|Zn2+(_aq_) || Cd(_s_)|Cd2+(_aq_ (Zn(_s_)|Zn2+(_aq_) || Cd2+(_aq_)|Cd (s Cd2+(_aq_)|Cd(_s_) || Zn(_s_)|Zn2+(_aq_ Read more
