A cell utilises the following reaction: 2CO^(3+) (aq)+Zn(s) to 2CO^(2+)(aq)+Zn^(2+) (aq) What is the effect on cell emf of each of the following changes? Co(II) nitrate is dissociated in the cathode compartment. |

Answer» Solution :For the GIVEN cell, we have `E_(cell)=E_(cell)^@-0.0591/2log""([Co^(2+)]^2[ZN^(2+)])/[Co^(3+)]^2` USING the above QUESTION, we know that if `[Co^(2+)]` is increased `E_(cell)` will decrease. |
