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
@@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
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.
The sound of his pen is violence.
I am a french student and this video was extremely helpful... Thanks to you, I am now able to understand the notion of pKa ! ;)
great video thanks
at 6:15 (conjugate base not acid)
Amazing video, deserves millions of views..
i am french and it's a good video to learn the difference between pH and pKa, thanks
Very helpful, thank you!
Thank you so much! I was struggling because I couldn't understand the difference between Ka and pKa.
Excellent!!
Taught with love and very helpful..thank you sir.
Wow......
Where was he during my biochem nightmare of a class???
:(
I finally truly understood pKa.
Thank you!!!

In 6:13 you're saying A- is a conjugate acid. Shouldn't it be a conjugate base instead?
you're right
Thank you!!
bro how u write that backwards?
Very helpful
Thank you
very educative. thank you regards
Is pka particular to a substance OR to a substance in a certain reaction/solution?
Great video
It's helpful. Thanks
pK What is the abbreviation?
great explanations, thank you!
Thank you! Very helpful :)
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

awesome video, thxx
So how do we measure Ka in a lab?
Good question
It's calculated given the concentration of the reactants...
You guys learn it in universities while we learn it in high school
Who’s we?
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
THE BEST VIDEO EVER
Thanks Sir
merci beaucoup...(thanks)
I can't stand the sound of pen
Very helpful, thank you!
