In this lesson you will learn what oxidation is and why it is important in chemistry. We will learn that oxidation is defined to be when a substance in a reaction loses electrons.

think in terms of charge; if an electron is 'negative' then the more electrons the more the charge is 'reduced'...... reduction in charge when recalling that electrons are negative will help you connect the word reduction to gaining electrons.
once again,fantastic,dint no any of this stuff,just sinking in with ease and no headachs,thats a credit to you,jason,great lesson,thank you.
It's so hard to find the lessons that go next they all say first lesson but it's finding one after the next
hlo
I've already taken some college chemistry but now at 46 regained an interest in it. Of course I remember little... came here and found these videos. This is the best instructor I have ever seen for a lecture! I could find all of this information on youtube already, but I'm STILL considering buying these DVD's only because the instructor is fantastic! So many things that still confused me are now perfectly clear!
Thank you very much! Good luck in your studies!

I don't know what I will do if you not around." Your lecture is so awesome."
Thank you for taking your time! Thank you for being thorough!😅
Sir, may you live 80 more years

Ok. "Oxidation". "Gives Electrons".! Because it has too many --Negatively charged Electrons. Giving it a net -Negative charge.! And is therefore known as an Oxidizer. Regardless of whether or not the oxidizer was Oxygen.!
And a "Reduction". "Takes Electrons".! By having a net + Positive charge.! Which is the lack of Negatively charged Electrons.
But anything with a Net --Negative charge. Is refer to as "The Reducing Agent". Because it's the thing Losing electrons.!
And anything with a Net +Positive charge. Is refer to as "The Oxidizer Agent". Because it's the thing Taking Electrons.!
And a "Redox" reaction is a combination of both.! Which occur simultaneously. So whenever one happens so to does the other.
I appreciate your patience.
P.S. It may have been more helpful to write on the board and say. @16:40.
" Oxidation = The loss of Electrons.
And a "Oxidizer" is the substance losing those Electrons.!
And "Reduction" = The "Gain" of Electrons. Because it has "Reduced" the Oxidizer.! "
Because writing it the way you wrote it was confusing for me.!
It was only through your examples and analogies that I finally understood.
If you had said.
" For instance the way "Rust" is created. When the Net Charge of the Iron Atom becoming neutral. Because the "Oxidizer" undergoes "Reduction".
Causing the Oxygen Adams to give up electrons. To the Iron Adams.
And that it is actually the Oxygen Atoms Which is the "Reducing Agent". Because it is undergoing "Reduction". And Giving Electrons.
And it is actually the Iron Adam. That is the "Oxidizing Agent". And undergoing "Oxidation". Because it's Taking Electrons.
(But what a ridiculous misnomer "A".!)
Causing the Iron Adam to not interact with the rest of the Iron Adams in the same way. Causing it to break down because it has been "Oxidized" or undergone "Oxidation". "
I don't know. Maybe it's just me. But I think I would have understood it more easily if it were written and said like that.
Again thank you for your patience.!
Profesor do you have a class about formula mass, composition of compounds chemical formula from experimental data..? BTW, you are awesome !
Wow stressing out. Thanks this make sense.
We had so much FUN in our CHEMISTRY LAB way back 56 years ago . I can remember the orange color as the process of e- losses and e - gained but at the end of our CLASS , we still can not fully understand why it happened..
That is why I liked CHEMISTRY . Sir Jason thank you , the CHEMISTRY FUN is life time....
At that time we were confused of REDUCTION AND OXIDATION..
Not anymore with your kind guidance Sir at least , we look forward the DONOR and the ACCEPTOR ..
Mg + O2...>> MgO
Again , Thanks a lot...I am crazy on Chemistry subject with a better grade..
Don't mind me, just wondering about chemistry terms... I know it's supposed to identify what's doing what in the reaction, but couldn't they have used something simpler like electron loser, electron gainer? Or at least not using the opposing term in another vocab word would be less confusing (the fact that what was oxidized is the reducing agent.) It's already confusing to stop associating reduce with its general definition. I think of reduction as reduction in charge, but I get why electrons are used in the definition since you keep track of them.
I read that oxidation is called that because oxygen was the best known element at the time to take away electrons. It's interesting, but it also makes it seem like oxygen would be involved. Chemistry language is confusing sometimes.
Very good. Thanks 👍
Very helpful indeed
LEO the lion says GER. Lose electron Oxidation, Gain electron Reduction. That's how someone explained it to me years ago but this is great review. Thanks.
So this is where science and trigonometry go together
very good ,sir.thanks keep it up
Please explain once more about the area how to balance the equations
You're the best tutor
THANK YOU... SIR...!!!
It is a needed Revision...!!!
Thanks lecture i understood your lession deeply
Great job sir, love from India
How to know whether the element is gaining or loosing electron?
If only people knew how dire this knowledge is to their daily life.
Nice!
Thank you!

Lesson are all over and hard to find the sequences of the lessons.
Thank
lol i am trying to find an anwer for my test
OILRIG-Oxidation is Loss Reduction is Gain.
Awesome! Good way to remember it.

OMG THANK U
I gonna be like you lecturer
Thanks you but I will like to go back at areas o balance of equations
Nice
I didn’t understand I just want someone to get straight into the point and tell what is it
Look up a channel called Peter & Pete, totally destroying mainstream chemistry. you wont pass any test's with the info though, but you'll fully understand the bs in mainstream chemistry.
it so hard to find the meaning of oxidation
For real
I see "Oxidation": Ok, it has to involve oxigen or oxide or something relative.
Science: Has NOTHING to do with oxigen. Its about an atom gaining a positive charge.
Me: Then name it according or relative to what it is!!! Positation, Cationizing, Increment, I don't know, something that intuitively gives the concept! At least Reduction gives the idea of a decrease in electric charge.
Incre-Decre reactions?
This atom cationizes while this other anionizes... Ionizing.
Umm I just asked waht is oxidation so.. just tell us straight up
Explaining long Time same thing. Repeating is long
*rolls eyes*
*rolls eyes* nerds pfft
Good explanation but please talk less and go straight to the point
As we are going further views are getting less.
To long..
Too
