Which one of the following conditions will increase the voltage of the cell represented by the equation ?A. Increase in the dimension of Cu electrodeB. Increase in the dimension of Ag electrodeC. Increase in the concentration of `Cu^(2+)` ionD. Increase in the concentration of `Ag^(+)` ion |
|
Answer» Correct Answer - D Cell voltage will increase, either by increasing the concentration of `Cu^(2+)` ion or by decreasing the concentration of `Ag^(+)`. `Q=([Cu^(2+)](/([Ag^(+)])` Lesser is the value of Q, greater is the cell volatge. |
