Question 4 2 pts Using the virtual lab above and Appendix C in your lab manual, complete the following statement Note: Record the values for the spontaneous reaction. A Ag/Ni voltaic cell has an Eo of V. If you change the concentration of the solution in each cell to 0.01 M, the EMF is V. This change is because the standard potential, Eo is defined at M, so K, atm, and differing from those standard conditions will change the observed...
