Calculate the number of coulombs delivered by a Daniel cell, initially containing 1 litre each of 1M Cu^(2+) and 1M Zn^(2+) ion which is operated until its potential drops to 1V. E_(Cu^(2+),Cu)^@=0.34V, E_(Zn^(2+),Zn)^@=-0.76V |

Answer» Solution :For the DANIEL cell : `ZN, Zn^(2+)||Cu^(2+),Cu` `E_(cell)=E_(RHS) (RED.)- E_(L.H.S) (red.)` |
