Hello, everyone. Thanks for joining as we take a quick look at what makes an oxidation reaction, actually an oxidation reaction, oxidation reduction reaction. So we're given three equations and were asked to identify which two of these three are oxidation reduction, which to our Redox and the third is not were asked to identify the reaction type. Okay, so I'm going to go to an orange, and an oxidation reduction reaction is going to have a couple substances that change oxidation numbers. And the easiest thing to Dio is to look to see if you have any pure elements on one side and then have an eye on on the other side. What do I mean? Let's look at elemental zinc, which has an oxidation number of zero, and zinc, which has an oxidation number of two plus. So zinc has a change in oxidation number. That's me means that it's undergoing oxidation, So zinc is losing electrons as it goes from zero to a two plus. So it is being oxidized, and another one to look for is nitrogen. Nitrogen frequently is a substance that we're looking at. I think I'll use a green for this one, so Let's take a look at first. This nitrogen, the oxidation number for this nitrogen has to be positive for Take a look. You should see that. That has to be a positive four. And over here, since, um, I have a negative to I'm gonna write this over in this little area and all three minus. Since this is a negative to have a negative six, but that should be a negative one minus. This has to be a positive five. So that's a plus five and is gaining. So it's going from a plus five to a plus four. Therefore it is reduced. Number one is an oxidation reduction reaction. Um, in number two, let's go ahead. And a sign Oxidation numbers. My zinc is combined here for a two plus. And over here, two plus, I'm gonna leave sulphate as an ion that's two minus. And myself. It right here is two minus. So that's takes care of those. My hydrogen right here is one plus. And here it's one plus. And here it's one plus and my oxygen is too negative. So to negative, there's no change of oxidation. This is not an oxidation reduction reaction and What type of reaction is this? This is an acid base reaction. It's an acid base neutralization, which is a specific type of a double replacement. It's just a, um, type of double replacement. And last but not least, let's take a look at our third equation. That should be a three, not a beat. Um, here we have elemental Kelsey, and so it zero. And here we have combined Kelsey with a two plus. So calcium is losing electrons. Therefore, it is being undergoing oxidation, and, um, my oxygen is too negative on each side. My h hydrogen is one plus here hopes there. It's un combining zero. So H is gaining electrons as it goes from a plus one to a zero. So it is undergoing reduction and thanks for listening.

Hi everyone. So feature reactions. Our redox reaction A B and 03 toys. Yes, plus K two years so forth gives BSL four solid plus stories. Can or three acquiesce now basically. What a redox reaction. Redox reactions reactions which in walls any actions reaching laws and was simultaneous um Yeah. Yeah, simultaneous. Right. Yeah oxidation and reduction. What long situation and put it up A sham. Yeah. Are called get it up scratch their stocks reactions and yeah. Yeah. You know. Yeah. Among these reactions reaction B and D. Yeah the reactions B and B are relax reactions. Mhm reelections redox reactions uh you know be mediation, My teeth, calcium salad plus cl two gas gives See AC. L two selene. Now here oxidation state of calcium in zero that of chlorine is so zero but here it is flushed two and chlorine is -1 for each chlorine. So oxidation state Africa is here. Okay. Changes from zero to plus two. And data picked. Lorene changes from zero to minus too far to chlorine For every blowing -1 and therefore calcium. Another goal. Yeah. Yeah. Can the same undergo oxidation. Okay aims chlorine undergo the reduction Conuction and they're 40 busy redox reaction. Then we'll see p reaction deviations. The reaction is Miss Sharon Stlead plus If he two plus agrees Utes in seven two plus a Prius plus F E solid zero now. Yeah. Now, you know in this case is soul networking Sink Oxidation State is zero. Then I ran observation straight is zero the zinc oxidation states and this from No 02 Plus two. So it is yeah, oxidation increasing the oxidation of Marie's oxidation. And if it took place in 20 and that's why Iran and I'll go reduction and never got reduction. Okay. Now the reaction. Yeah, A m C mm. The exam. Yeah. Lean any exertions. A and see I'm not redox reactions reaction because if you see if a reaction Miriam native plus Kato. s 04 gives barium sulfate plus toys cannot. So in this case, both that is oxidation state of burying these two plus in reaction product also two plus operation plus one in the reactant plus one in the product and that. So it is not a redox reaction. Then D even if it's see properly mm uh receiving at cl plus an H. Usually store plus initial clothing oxidation state in minus swimming reacting minus one in the product, going sodium plus one in the reaction plus one in the product. And that's way reaction AMC. They're not really.

Let's indicate which reactions are redox reactions for a E is not a Redox reaction. A is a precipitate formation reaction for be. This is a Redox reaction, and the reason why here is we have a metal calcium. Reacting with a nonmetal chlorine for C. C is not a Redox reaction. C is in acid base. Neutralization reaction and for D is a Redox reaction, and this is because there is a transfer of electrons between the react mints going from Zinc two f e two plus.

To identify a reaction of re doctor. Non Redox reaction is helpful to assign oxidation states and then see if the oxidation states for various elements changed. We see that magnesium in this case goes from zero 22 plus and stink goes from two plus 20 So this is definitely a redox reaction. The 2nd 1 we have hydrogen going from a zero oxidation state, two plus one and then oxygen going from plus two minus two. So also definitely a redox reaction. The next one we have the oxidation states of everything staying constant, so because they all are constant, this is not a redox reaction. Then we have calcium oxide reaction with water making calcium hydroxide, and we see that the oxidation state of calcium stays the same, that of hydrogen and oxygen states the same. So this is also not a redox reaction. Then we have calcium chloride reacting with ammonium phosphate producing ammonium chloride and copper phosphate. And when we assign the oxidation numbers, we see that none of them change. Therefore, this is also not a redox reaction. Then on the last one, we have methane gas reacting with oxygen gas producing carbon dioxide, gas and water. Carbon goes from an oxidation state of minus four to plus four. So this is definitely a redox reaction, and oxygen goes from zero to minus two.
