In the Brønsted-Lowry definition of acids and bases, an acid is a proton (H⁺) donor, and a base is a proton acceptor. When a Brønsted-Lowry acid loses a proton, a conjugate base is formed. Similarly, when a Brønsted-Lowry base gains a proton, a conjugate acid is formed. A Brønsted-Lowry acid (or base) and its conjugate base (or acid) are known as a conjugate acid-base pair.

the best way to remember this is DAAB! donor-acid and accepter-base.

You are one of the best teachers in World for me. And I want to say a hearty thanks to the Khan Academy team for working for us.

SkarrowJr. He writes things down prior to video

The scripts are written by other teachers as well which he gives credit on the website

@shafa9949 3 года назад

thank you so much to Khan Academy for clearing the doubts of the students...... and to teach us in the easiest and the best way so we could understand

@catastrophe2155 2 года назад

So donor is acid. And acceptor is base. Understood :) I feel so confident for chemistry exams now. Thank u :)

@bananabird7584 4 года назад

3:38 why is he saying "both of these electrons in this pair" when hydrogen can only have 1 if bonded with a chlorine atom?

@annsmahboob3495 4 года назад

There will be one electron from the hydrogen and one from the chlorine to form a shared 'pair' of electrons.

@jaskaransingh6440 7 лет назад

u r just next to awesome

@LesleighA_ 3 года назад

thank u for this

@wanwai7467 8 лет назад

I still don't understand why is in the HCL , the electrons are grabbed by the chlorine atom? is it because of the electronegativity?

@prasispoudel7353 8 лет назад

yes

@esskayesss69 6 лет назад

Yep!

@cieprosuhas4557 5 лет назад

Yes.. Because electronegativity is the tendency of an atom to draw electrons closer to it. Chlorine is more electronegative and therefore chlorine takes the bond pair.

@AIBImaadHasan 4 года назад

yes

@katarinapavlic1296 8 лет назад

What the hell is the difference beetwen Arrhenius's and Bronsted-Lowry's theory??

@danishashar4861 7 лет назад

Well this theory doesnt just limit a base to something that gives OH- ions. It can be base without releasing hydroxide or an acid without having the typical HCl kind of acid. Like water can be an acid or base in this theory , depending on the other chemical. I am a little late tho Lol

Does the base have to be water or can it be an other molecule as well?

it can be also other molecule

@aylora7033 5 лет назад

sir, if you could please explain to me the reason behind the hydrogen's electron being given up to chlorine and how can the h20 obtain a proton and how it did bond to hydrogen. please answer my question. ps: your explanation was very clear and straightforward. thanks for not using complicated words.

H3O+ is formed by coordinate bond

@alexgilbert1435 4 года назад

great video thanks!!

@higurusakiyokamamoto 6 лет назад

At 4:03 he says that the water forms a covalent bond with the H+ from HCl, isn't that a dipole dipole hydrogen bond? is it an intra molecular bond?

@TheVompom 6 лет назад

It's a co-ordinate bond (also called a dative covalent bond) is a covalent bond (a shared pair of electrons) in which both electrons come from the same atom

@premlatasingh690 5 лет назад

@punnyarthabanerjee3496 6 лет назад

chlorine would have 7 electrons of its own nd it shares 1 electron with hydrogen
