Use the References to access important values ir needed for this question. Enter electrons as e Use smallest possible integer coefficients for ALL reactions. If a box is not needed, leave it blank. A voltaic el ical cell is constructed in which the anode is a Cu cut half cell and the cathode isa Ag lAg half cell. The half cell compartments are connected by a salt bridge. Write the anode reaction. 2e Write the cathode reaction. Ag Write the net cell reaction, 2Ag 2Ag Cu In the external circuit, electrons migrate to the Ag'l Ag electrode from B the Cu Cu electrode. In the salt bridge anions migrate to B the Cu Cu compartment from B the Ag Ag compartment.Explanation / Answer
Anodic reaction : Cu---> Cu^2+ + 2e-
Cathodic reaction : 2Ag+ + 2e- ---> 2Ag
----------------------------------------
Overall : Cu + 2Ag+ <==> Cu^2+ + 2Ag
---------------------------------
In the external circuit the electrons will migrate to Ag/Ag+ from Cu/Cu^2+
in the salt bridge anions mifrate to Cu^2+/Cu compartment from Ag/Ag+ compartment
