1.	Formulate the galvanic cell in which the following reaction takes place: `Zn(s)+2Ag^(+)(aq)toZn^(2+)(aq)+2Ag(s)` State (i) Which one of the electrodes is negatively charged? (ii) The reaction taking place at each of its electrode. ltBrgt (iii) The carriers of current within this cell.
Answer» The cell reaction is : `Zn(s)+2Ag^(+)(aq)toZn^(2+)(aq)+2Ag(s)` The cell is represented as: `Az(s)\|Zn^(2+)(aq)\|\|Ag^(+)(aq)+Ag(s)` (i) Anode i.e., zinc electrode is negatively charged. (ii) At anode: `Zn(s)toZn^(2+)(aq)+2e^(-)` At cathode: `Ag^(+)(aq)+e^(-)toAg(s)` (iii) Within the cell, the current is carried by the cations and the anions through the salt bridge. In the external circuit, electrons flow from zinc to silver and hence conventional current flows from silver to zinc.
