A concentration cell is an electrochemical cell where the anode and cathode have the same metal electrode and the electrolyte but the concentration of electrolyte in anode and cathode cells is different.
We are provided with the cell notation for zinc-based concentration cell.
A cell notation is a shorthand way of writing a chemical reaction that occurs inside an electrochemical cell.
The voltage generated by the zinc concentration cell described by,
Zn(s)|Zn2+(aq, 0.100 M) || Zn2+(aq, ? M)|Zn(s)
is 19.0 mV at 25°C. Calculate the concentration of the Zn 2+(aq) ion at the cathode.
