In a galvanic cell, the following cell reaction occurs : Zn (s) + 2Ag^(+ )(aq) toZn^(2+) (aq) + 2Ag (s) E_("cell") = + 1.56 V (a) Is the direction of flow of electrons from zinc to silver or silver to zinc ? (b) How will concentration of Zn^(2+) ions and Ag^(+ )ions be affected when the cell functions ? |

Answer» Solution : (a) Flow of electrons will take place from zinc to SILVER. (b) The REACTION takes place as under: `Zn + 2Ag^(+) to Zn^(2+)+ 2Ag` THEREFORE concentration of `Zn^(2+)`ions will increase and that of `Ag^(+)` ions will decrease |
