Copy and paste link to view the salt bridge graph


Answer the following questions regarding the electrochemical cell shown. A portion of the standard reduction potential table is given below.

L+ + e- → L     E° = 0.20 V

R2+ + 2e- → R   E° = 0.90 V

(a) Write the balanced net-ionic equation for the spontaneous reaction that occurs as the cell operates, and determine the cell voltage. 

(b) In which direction do anions flow in the salt bridge as the cell operates? Justify your answer

(c) If 10.0 mL of a 3.0-molar R(NO3)2 solution is added to the half-cell on the right, what will happen to the cell voltage? Explain.
