Question

Enter electrons as e. A voltaic cell is constructed in which the anode is a Cr Cr3+ half cell and the cathode is a SnSn2+ half cell. The half-cell compartments are connected by a salt bridge. (Use the lowest possible coefficients. Use the pull-down boxes to specify states such as (aq) or (s). If a box is not needed, leave it blank.) The anode reaction is: The cathode reaction is: The net cell reaction is: + + In the external circuit, electrons migrate - the SnSn2+ electrode the CrCr + electrode. In the salt bridge, anions migrate - the Sn|Sn2+ compartment - the Cr|Cr3+ compartment.
