In the electrilysis of an aqueous cupric bromide solution, how many grams of bromine are formed on passing a current of 1 ampere for 16 minutes and 5 seconds ? Write the anode and the cathode half reactions.

Answer

0.80 g; cathode reaction `Cu^(2+)+2e^(-) rarr Cu`;
anode reaction `2Br^(-) rarr Br_(2)+2e^(-)`
