Accepted Answer

Welcome back everyone in this example, we're told that under standard conditions, list of following oxidizing agents. And in an acidic solution in order of increasing strength and were given the below species in all of their reduction reactions. We know that these are all reduction reactions because we recognize that electrons are added on the reactant side. And when electrons are added on the reactant side, we know that the equation is a reduction were also given the reduction potentials for each of these species. And we're going to recognize that since we need to label these oxidizing agents in order of increasing strength, we're going to begin with the weakest oxidizing agent. And we're going to end our ranking with the strongest oxidizing agent. And so we're going to recall the trend that based on a increasing electric or sorry, reduction potential as the reduction potential increases. This corresponds to our substance that is easily reduced. And we would recall that if a substance is easily reduced, it's going to be a stronger oxidizing agent. And so now that we have this understood, we also want to recognize that we have to repeat equations. We have two equations for manganese for oxide, we also have two equations for nitrogen gas. We're going to and let's use a different color for the equations for nitrogen gas. So looking at the reduction potentials, we're going to cancel out one set from or one reaction from each of these two repeat sets. So we're going to determine how to cancel that out because we know that we're organizing reduction potentials that are lower associated with weaker oxidizing agents versus reduction potentials that are higher associated with a stronger oxidizing agent. And so we're going to see that based on our manganese for oxide equations, The lower reduction potential is .59V. And so because this is a lower value, this means that manganese for oxide is acting as a weaker oxidizing agent according to this reaction. So we're going to actually cancel out this entire reaction because we don't want to consider it in our ranking. Moving on to our next set, which is our equations for nitrogen gas, we have a lower reduction potential of negative 1.16V. It's more negative than the first reduction potential for nitrogen gas. And because again, we want our ranking to only include strong oxidizing agents. We're going to rule out this equation as well from our ranking. And so now that we've ruled out these two equations, now we want to rank our five species from weakest to strongest. So finding our next lowest oxidizing or reduction potential. Rather we're going to see we have a value of negative 0.23 volts, which is our most negative reduction potential value. And so this would rank as number five being the weakest oxidizing agent, which is nitrogen gas here. Now we want to so we'll start that off in our ranking nitrogen gas is a because of its most negative reduction potential value. It's going to be the weakest oxidizing agent. We're then going to rank our number four, which is our second most negative as our reduction potential value of tin. To caddy on. Where? Or the 10 2 plus Catalan sorry, where we see we have a reduction potential of negative 0.14 volts. And so even though it's still a pretty low reduction potential value, we would say that the 10 2 plus catty on is a stronger oxidizing agent because of its greater or less negative reduction potential value compared to nitrogen gas. Now ranking as number three, we find the next most positive reduction potential value, which is going to be 0.45 volts. This ranks as number three and it's associated with sulfurous acid here. So we would say that sulfurous acid is a stronger oxidizing agent because of its more positive reduction potential value of 0.45 volts compared to the tin two plus catty on. And now ranked as number two, we have the value of 20.107 volts. Sorry, this is number two associated with bromine gas. The di atomic form of grooming or brushing liquid. Sorry, not gas. And so we're going to now realize that roaming liquid has a higher reduction potential because of its more positive Or because of its more positive reduction potential of 1.7V. It's a stronger oxidizing agent than sulfurous acid. And so now ranking as number one in our final answer, we would see that number one is attributed to the reduction potential value of our manganese for oxide, which is the most positive reduction potential value of positive 1. volts corresponding to our manganese, four oxide as the strongest oxidizing agent. And so for our final answer, we have the below ranking where again our nitrogen gas is our weakest oxidizing agent, and our manganese for oxide is our strongest oxidizing agent. I hope everything I reviewed was clear. If you have any questions, leave them down below and I will see everyone in the next practice video.
