Consider the figure and answer the following question. (i) Cell 'A' h as E_("cell")=2V and Cell 'B' has E_("cell")=1.1V which of the two cell 'A' or 'B' will act as an electrolytic cell. Which electrode reactions will occur in this cell? (ii) If cell 'A' has E_("cell")= 0.5V and cell 'B' has E_("cell")=1.1V then what will be the reactions at anode and cathode?

1.	Consider the figure and answer the following question. (i) Cell 'A' h as E_("cell")=2V and Cell 'B' has E_("cell")=1.1V which of the two cell 'A' or 'B' will act as an electrolytic cell. Which electrode reactions will occur in this cell? (ii) If cell 'A' has E_("cell")= 0.5V and cell 'B' has E_("cell")=1.1V then what will be the reactions at anode and cathode?
Answer» SOLUTION : (i) Cell 'B' act as electrolytic cell due to its lesser value of EMF. Theelectrode REACTIONS will be Atcathode `Zn^(2+)+2e^(-)rarrZn` At anode `CurarrCu^(2+)+2e^(-)` (ii) If cell 'B' are higher emf, it acts as galvanic cell. Now it will push electrons into cell 'A' In this CASE, the reactions will be `ZnrarrZn^(2+)+2e^(-)` (At anode) `Cu^(2+)+2e^(-)rarrCu`(At cathode)
