Question

A voltaic cell is constructed in which the following cell reaction occurs. The half-cell compartments are connected by a salt bridge. 2Ag+ (aq) + Cu(s) + 2Ag(s) + Cu2+ (aq) The anode reaction is: The cathode reaction is: + In the external circuit, electrons migrate the Ag|Ag+ electrode the Cu Cu2+ electrode. In the salt bridge, anions migrate the CuCu2+ compartment the Ag|Ag compartment.

Answer 1

Given reaction Ragt (a) + Cu (s) - QA965) + Cuth (aq) A node At anode olidation takes place. CU(s) cute (aq) + a é Coxidation). 'cu' acts as anode. cathode reaction! Reduction takes place at Cathode. Agt (aq) + ē AJ(s). At anode exidation takes place. cu oxidised to cutions, which go into the solution, and relases a electrons. The released electrons at the anode, travel re through the external circuit to the cathode jue.
