The cell consists of a Co2+(aq, 0.740 MİCo(s) half-cell connected to a Co (aq, 2.30x103 M)Co(s) half-cell. Determine which half-cell will be the cathode compartment and calculate the cell voltage. The Co2*concentration in the cathode compartment will be: a. 0.740 M b. 2.30x10-3 M ell

Enter electrons as e A voltaic cell is constructed from a standard Ni2+ Ni half cell (Ered = -0.250V) and a standard II half cell (Ered = 0.535V). (Use the lowest possible coefficients. Use the pull-down boxes to specify states such as (aq) or ($). If a box is not needed, leave it blank.) The anode reaction is: The cathode reaction is: The spontaneous cell reaction is: The...
