A concentration cell consists of two Zn/Zn²* half cells. The electrolyte in compartment A is 0.100 M Zn(NO:)2 and in compartment B is 0.101 M Zn(NO3)2. A salt bridge is made with a NANO3 solution. 2. a). Identify and balance the ½ reactions and write the overall balanced net ionic equation representing the total cell reaction. b). Draw a neat diagram to represent this cell, showing and labeling all necessary components including: anode, cathode, electron flow, cation flow, anion flow and charge on the electrodes. c). Write the shorthand cell notation for this cell.
