This video provides a comprehensive introduction to Redox reactions, a fundamental concept for 11th and 12th-grade chemistry. It explains that a Redox reaction occurs when both oxidation and reduction happen simultaneously within the same chemical reaction. The lesson breaks down the specific criteria for identifying these processes through oxygen transfer, electron movement, and the addition or removal of specific elements.
So, how are you all today? I'm here for you.
I am going to explain what a redox reaction is.
Redox is a very important concept for our 11th and 12th grades.
Here is the child today
I mean, Redox is made up of two words.
I mean, if you listen carefully to any reaction
Yes, in any reaction, oxidation
Even if it's happening, let me tell you what oxidation means.
If oxidation is also taking place in any reaction,
and the same reduction is also occurring in that reaction, okay,
It should be in the same reaction, if reduction occurs in the same reaction.
It is also happening, and oxidation is also taking place, so the child refers to it as such.
So that's what the child calls a redox reaction.
Right now I'm going to tell you about oxidation.
What does it mean to listen carefully, child?
What does oxidation mean here? I've
Everything has been written regarding all oxidation-related topics.
Keep in mind the point of view if anyone ever
Oxygen is being added in the reaction, that's correct.
I'll tell you how to do it, I'll let you know, I'll inform you.
Also check whether oxygen is added in any reaction.
If it is happening, you can call it oxidation.
The second point is the addition of the negative element of electricity, you
So, the most electronegative element is fluorine.
I am the child, you all know, your sulfur, your fluorine
What is your chlorine, your oxygen, all of this?
Electronegative atoms are present, so if these are also involved in any reaction
Shout out if you're being oxidized.
Second removal of a hydrogen atom
Yes, if hydrogen is being released in your reaction.
As in the case of H2S, H2S
First in the reactant
And when I went to the product
So H came out of it.
Only sulfur remains.
So H came out, don't remove "hua na"
So oxidation has occurred there, okay
and last, second to last
removal of electropositive metal
What are electropositive metals?
Hey kid, the metals in your S block are
They are electropositive metals, so
Who all? Say yes
sodium, potassium, calcium, magnesium
These are all your electropositive metals.
If they are coming from somewhere
So, tell me, is oxidation taking place there?
Okay, and the last one regarding oxidation
It explains very clearly.
and that is nothing but what
Oxidation means loss of electrons.
What do they say if a species loses its electron?
If you are experiencing a loss, that is called a "loss."
Yes, oxidation did not make sense to you.
As I'm telling you, suppose you have
Sodium is a child; what is the atomic number of sodium?
11 is 11, it is not 11
Okay, first fill 2 in the shell, second fill 8 in the shell,
And finally, how much will you fill, one?
And the child, that last electron, will lose energy.
And if this metal loses this electron,
Then the metal will acquire a positive charge.
And what will he do with his one electron?
will lose it because you all know whose outer
In the most shells, if there are up to 3 electrons in one shell, then that
If it loses, and it loses again, then the child has become the loss itself.
The oxidation state of an electron is called what?
I've already mentioned the points regarding oxidation; the second one I'll give to you.
If I tell you about reduction, the child doesn't understand anything about reduction.
You must remember it completely backwards, what exactly must be remembered backwards?
A child, reduction is the exact opposite of oxidation.
I mean, look, what did you read here—addition of oxygen,
So, read here: removal of oxygen, what was written here,
addition of negative element, read here
atomic number of fluorine
How much is it?
like a ripper
Will accept, will take, then fluorine here today reduction
It's also doing it, okay, come on, let me show you some examples.
I'll explain it to you in a fun way here.
Here comes the child, here is the first example in front of you, coming in, okay?
Here
Look, you
example
How would I know?
It is moving.
Look, I'm adding O2 inside this carbon.
In addition, that is the oxidation reaction.
Look here, it's magnesium.
What should I do inside magnesium?
I am adding oxygen.
I have Fe2O3, which reacted with carbon.
And look, its O has disappeared, only Fe is left, where did the O go?
I have taken it out, so removal, removal of oxygen,
I have removed oxygen from this compound.
and that is what it is; we will call this saving reduction.
You can understand some reactions the way they were before,
Yes, oxidation is taking place here, and what is happening here?
Look carefully—there's not much space here.
It happens sometimes, but how would you know if you're satisfied?
It is said that all this was told by Adri Cloriz to Sacheli Wujikot people.
And therefore it does not happen, then Enegz through this very means
And it's decreasing. Let me tell you how.
Listen carefully: how many electrons are in the outermost shell of sodium?
It is an electron, a child, an electron, and
Sodium causes the electron to lose.
Which one got the positive charge on it?
What's happening here now is loss of electron,
what was stated about loss of electron, what was stated about loss of electron,
The child said oxidation, which was exactly what was stated earlier, okay sir, I understand now.
Here, electron loss occurred; sodium lost one electron.
Sodium has one electron in its outermost shell.
He lost it, and that's where it ended.
The atomic number of sodium is 11.
First, I filled 2, in the second one
8 filled, last one a child
Filled 7 electrons, 7 means
Very close to octet, very close to 8
Closer, it will behave like an electron acceptor.
That will become 8, then here
Chlorine accepted 1 electron, and
What happened to the chlorine here, my chlorine?
What did gain of electron do? What did it do?
Gain of electron is correct and gain of electron
What happens during reduction? Okay, so in anisyl...
What are you saying, kid? What are you doing in the anus?
redox reactions are those where
a loss of electrons is also occurring, and
a gain of electrons is also taking place, such cases
It's the reactions that the child learns to speak, yes
redox reaction, so simple
tips and tricks, or rather
organic chemistry, or rather about chemistry
