Question
72) Consider the following standard reduction potentials, Al3+(aq) + 3 e--Al(s) E"=-1.66 V 126) + 2 e- 2 I-(aq) E= +0.54 V 10 Under standard conditions, aq) is a stronger oxidizing agent than 126), and I-(aq) is a stronger reducing agent than AIG) 20s) is a stronger oxidizing agent than Al3+(ag),and Al) is a stronger reducing agent than F-(aq) C) Al(s) is a stronger oxidizing agent than -(ag), and Al3t(aq) is a stronger reducing agent than 12(s). D) I-(a) is a stronger oxidizing agent than Al(s), and 12(s) is a stronger reducing agent than Al3+(aa)Explanation / Answer
A species which is reduced during a redox reaction is called oxidizing agent. Higher the reduction potential stronger will be the oxidizing agent. Since, reduction potential of I2 is greater than the reduction potential of Al3+(aq), so, I2 is stronger oxidizing agent than Al3+(aq).
A species which is oxidized during a redox reaction is called reducing agent. Higher the oxidation potential stronger will be the reducung agent. Since,oxidation potential of Al(s) is greater than the oxidation potential of I-(aq), so, Al(s) is stronger reducing agent than I-(aq).
