Interpretation Introduction Interpretation: The half-reactions that takes place at the anode and cathode for the electrolysis of each of the given aqueous solution are to be written: N a B r ( a q ) P b I 2 ( a q ) N a 2 S O 4 ( a q ) Explanation In electrolysis, two reactions occur at the cathode and the anode terminals of the cell. At the cathode, a reduction reaction takes place while oxidation reaction takes place at the anode. N a B r ( a q ) In the electrolysis of NaBr(aq), the reactions that took place at the cathode and the anode are as follows: A n o d e ( O x i d a t i o n ) : 2 B r − ( a q ) → B r 2 ( a q ) + 2 e − C a t h o d e ( R e d u c t i o n ) : 2 H 2 O ( a q ) + 2 e − → H 2 ( a q ) + 2 H O − ( a q ) P b I 2 ( a q ) The half-reactions that take place at the cathode and the anode in the electrolysis of the P b I 2 ( a q ) are shown below: A n o d e ( O x i d a t i o n ) : 2 I − ( a q ) → I 2 (
