Voltaic Cell V Voltmeter Wire- Ni electrode- Salt bridge -Zn electrode A. NiCl2 ZnCl2 Write the half-reaction that takes place at the nickel electrode: B. Assuming T=298K, and 1M concentrations for all solutions, what is the magnitude of the voltage displayed by the voltmeter? C. Which of the following true when the voltaic cell is operating spontaneously? Circle all that apply. i. The concentration of nickel ions increases. ii. The concentration of the zinc ions increases. iii. If the cell is left on long enough, the voltage read by the meter will change. iv. Removing the salt bridge will stop the flow of electric current. v. The electricity generated by the cell can perform work. vi. None of these is true.
