pure water is NOT neutral despite common misconception. Ions dissolved in water create solvation spheres around them and effectively lower the conc. of H+. pure water is infact acidic
If there is already a pH scale to define how strong the compound is acidic or basic then why they introduced pka value 😵😵🤕🥺 Is there any other use?? Anyways sir you explain very great 😁😁
pKa is more specific in that it helps you predict what a molecule will do at a specific pH. Essentially, pKa tells you what the pH needs to be in order for a chemical species to donate or accept a proton.
@@shreyas4858 Large Ka means MORE acidic, but large pKa means LESS acidic. Large Ka means that the concentration of products (hydronium and conjugate base) is much greater than concentration of reactants. This means that a lot of the reactants stayed dissociated and that the products are favored. Therefore, it means that the molecule is more acidic than a molecule with a lower Ka. To get pKa, you have to take the negative log of Ka. Therefore, high Ka meas low pKa. Since high Ka means high concentration of dissociated products, low pKa means more acidic. Conversely, high pKa means the molecule has a low Ka, telling us that the reactants were favored. Therefore, high pKa means that the molecule doesnt dissociate as easily
The sound of his pen is violence.
great video thanks
at 6:15 (conjugate base not acid)
Very helpful, thank you!
Amazing video, deserves millions of views..
I am a french student and this video was extremely helpful... Thanks to you, I am now able to understand the notion of pKa ! ;)
Excellent!!
i am french and it's a good video to learn the difference between pH and pKa, thanks
Thank you so much! I was struggling because I couldn't understand the difference between Ka and pKa.
Taught with love and very helpful..thank you sir.
great explanations, thank you!
Thank you!!
Wow......
Where was he during my biochem nightmare of a class???
:(
I finally truly understood pKa.
Thank you!!!
Thank you! Very helpful :)

It's helpful. Thanks
Great video
Very helpful
Thank you
very educative. thank you regards
bro how u write that backwards?
awesome video, thxx
This is very helpful :)
wondering how he can write upside down to teach
Perhaps he just reversed the video
is this man writing backwards the whole video
my thoughts exactly LOL
merci beaucoup...(thanks)
In 6:13 you're saying A- is a conjugate acid. Shouldn't it be a conjugate base instead?
you're right
Is pka particular to a substance OR to a substance in a certain reaction/solution?
You guys learn it in universities while we learn it in high school
Who’s we?
THE BEST VIDEO EVER
So how do we measure Ka in a lab?
Good question
It's calculated given the concentration of the reactants...
pK What is the abbreviation?

Thanks Sir
Sir, 8:23 large ka means higher acidic and lower ka means weak acid and then in list of compounds low pka turn higher acidic vice versa whyyyyyyy😭😭😭😭😭
it's the opposite, larger the Ka, less acidic is the substance
They are inversely related because of the -log
