a concentration cell is set up using two zinc wires and two solution, one containing 0.050 m zncl2 solution and the other containing 1.00 m zn(no3)2 solution. compute the potential of this cell.

Respuesta :

The  potential of this cell is +0.0385.

Zn | Zn2+(0.050 M) || Zn2+(1.00 M) | Zn

Zn(s) ==> Zn2+(0.050 M)       (oxidation on the left side)

Zn2+(1.00M) + 2e- ==> Zn(s)  (reduction on the right side)

Zn2+(1.00M) ==> Zn2+(0.050M)

Ecell = Eºcell - RT ln Q and assuming this situation is at 25ºC (298K), we have...

Ecell = Eºcell - 0.0592 / 2 log Q  

Q = 0.050 / 1.00 = 0.05

Ecell = 0 - 0.0296 * log 0.05

Ecell = -0.0296 * -1.301

Ecell = +0.0385  (note the potential is positive, meaning the reaction is spontaneous)

Also note that this is the INSTANTANEOUS cell potential. As time goes on, the cell potential will become ZERO.
