Consider the following substances: I2(s), Fe2+(aq), Cr2O72-(aq). Which is the strongest oxidizing agent? Which is the weakest oxidizing agent?

Question

Accepted Answer

well, everyone's in this problem. We're given Cl two and A plus S and H +20. And now these four were trying to identify the weakest and the strongest oxidizing agents. So for my standard reduction potentials, why has even brought up is because this is the tendency for something to be reduced. So what this means then is if we have a higher value, so a higher center reduction potential, this means that we have a stronger oxidizing agents. And of course that is exactly what we're looking for in this problem. So these are just the equations and values I have from my end. But of course it could either be in your textbook, found in online or even given to you by professor. So again, I'm starting off with Cl two because that's the first one listed here. So for my cl two, The reaction here is adding two electrons and this gives us two moles of cl -. The standard reduction potential will just put us e Is equal to 1.36V. Now for my N A plus so any plus, which is a curious here Adding one electron. This yields are neutral. Any And then of course our style reduction potential here is negative 2.71V. And then now for a sulfur, We're gonna go ahead and add two moles of H. Plus as well as two electrons. This yields H to us in. Its a curious state And the reduction potential here is equal to 0.142V. And lastly we have our H 20. So two moles of H 20 leader or is it a liquid state? We're adding two electrons. And this yields H two gas as well as two moles of R O h minus. So hydroxide. And the standard reduction potential here is negative 0.828 volts. Again where he said the higher the value, the stronger the oxidizing agent so we can see her out of all these different values. The strongest one then would be cl two with the value of positive 1.36. And the lowest values that we have is going to be our N A. Because I have a negative 2.71. So I have all the answer choices. Then the one that best matches our data and evaluation is going to be answered. De were the stronger the cl two in this cash a state and the weakest is going to be our N A plus. And it's a quest eight And again, d is my final answer for this problem.
