Question

What I have down is wrong, please answer if you actually know it

Half-reaction E° (V) 12(s) + 2e →→21"(aq) |0.535V 2H+(aq) + 2e → H2(g) 0.000V A13+(aq) + 3e + Al(s) -1.660V (1) The weakest oxidizing agent is: Al3+ enter formula (2) The strongest reducing agent is: (3) The strongest oxidizing agent is: I (4) The weakest reducing agent is: (5) Will Al(s) reduce 12(s) to I'(aq)? yes (6) Which species can be oxidized by H*(aq)? | | If none, leave box blank.

Answer 1

cn Just to understand erstand a a simple simple concept concept of of Reduction potential | Oxidation potential is that Higher the value of Reduction potential, means that Reduction is taking place. very easily ie if One ispecies is going under Reduction very easily It will act as Best oxidising agent for other, Similarly It Oxidation potential is quite High , oxidation is Happeening very smoothly & that Reactant specles then act as Best Reducing agent for others, Here. a Reduction Potential © Ig tde - 21109) 0,535 V © 2H+ (aq) +2 => Hz (9) 0,006 v. © At+(0q) + 3e -> Al(s) -1,660 v 000 Hare Reaction potential © is having value le Highest Reactant Reduction In . is Best oxidising agent your Answer (3) is locorect, similarly Reaction value ☺ is ie having lowest Reduction potential Reactant het is weakest oxidising agent. your answer (1) is also cageureat

Now let us Reverse QI (04) - Hz (9) -+ © Alls) → the Reactions Iq tale 2H+(99) +86 Aeto tse ☺ oxidation potential -0.535 V 0.000 V + 1.660 u 0.000 V Reaction . 6 de is having Reactant lowest oxidation II is weakest patenttal, Reducing agent . - your Answer (4) is wrong. Reaction - 0 is Hiring le pesctant Highesst oxidation Potential Alcs) is strongest Reeducing Agent your Answer (2) 15 also wrong. question 5 Now we have seen Alle) is strongest Reducing agent and In Reaction (1) Iz can easily be Reduced into I also Hence the answer is yes, Alls) can reduce In (2 to I (4) Question o 70 - Al can be easily oxidised by Ht because oni dation potential of Reaction ® is more the Reaction - Alis) is correct Answer
