One way of knowing acidic strength of organic compounds is to compare the inductive effects. A compound with a higher -I effect will have a higher acidity. A compound with a higher +I effect will be a weaker acid.
@@linsdesk7240 I haven’t found any videos on how to compare acidic strength when pka or ka values aren’t given. but my suggestion would be, Try to learn inductive effect and resonance effect, so by that we can compare acidic and basic strength by seeing the substituents attached to the given compound. And also try to memorise some common acids pka values like sulphonic acid, picric acid, carboxylic acid etc. If you have found any videos then drop the link of the video here if possible.
When we look at the formula: pKa=-logka, they look to be directly proportional to each other. How come the acid strength is increasing with a lower pka value and a higher ka value. Could someone please explain?
pKa is negative log(base 10) of Ka : pKa=-log10(Ka) when you multply both sides of eqation with -1 you have: -pKa=log10(Ka) => Ka=10^-pKa, so if you have greater value of pKa that means you power base of log ,which is 10, to greater negative value of pKa in orddr to get Ka value. So 10 powerd on greater negative value of pKa is actually smaller number and in fact acid is less stronger
a way you can calculation pka is with the henderson-hasselbalch equation. pka = ph + log ([acid]/[conjugate base]). i’m sure there’s another way, but that’s one of them!

Felt more like a math class than chem class. Dude needs to focus on the right stuff, too many too long pauses and in the end he didn't explain what pKa or Ka actually is.

Man what a voice! I can watch chemistry 7/7 24/24 😭
His voice is so calm and nice. His voice makes me relax and don’t worry about my upcoming organic exam. Keep up the good work!
@@HH-ss9vj i have the exam of organic tomorrow let's hope it goes straight
Why is his voice so soothing yet doesn't make you sleepy
i know im late but still, Thats because ORGANIC chemistry is soo intresting
exam stress
The important thing that i finally understood 😅
His voice makes me sleepy
@@meghand8634 those who disagree with this young man raise their hands ✋️
I saw the term "pka" in one of your other videos, googled it and was suggested this video. Can't believe how many videos you've made. Thanks for that.
words cant describe how grateful i am for you
Thank you 🙏 finally understand it
l follow you from Libya 🇱🇾
why is youre voice so relaxing :D
Thanks a lot bro I legit got a physical chem exam tmrw
Jay Mortality bet you failed you dosser!
@@thecasualfront7432 your comment doesn't make you seem much bright either
How come you got pka values of organic acids in physical?
@@abigailparry4191 equilibrium?
@@abigailparry4191 because acids & bases is part of physical chem but has applications in other areas of chem e.g. organic
Do you have a video about determining which compound would be the strongest acid, without a given pKa or Ka value?
YES I NEED THIS ONE WHERE WHERE WHERE
@@SomeKindOfTease have u found some?
@@linsdesk7240 theres this one trend ive been noticing where the molecule with fewer hydrogens is more acidic. Not sure if its always true tho

Hi miss
i do find those two equations at the last part of the video helpful. thank you very much. it's exactly what i was looking for.
Thanks sir
How can we compare Acidic strength when pka or ka values aren’t given.
Please do make a video on this if possible. Thanks.
Have u found some vid?

@@innerstoic-p7i i learn that in Hindi language (hindi + English ) by a teacher on TH-cam
Yeah I needed that formula thank you so much
How do you get the values of pKa and Ka? Can you please explain? thank you.
THANKS MAN!
You are the best
OChem tutor, you sav e my life. without you I would fail and become sad
larger pka means smaller ka, smaller ka means less acidic
for the first example:HCOOH more acidic than CH3COOH
thanks for the good explanation
Excellent lecture
is pka always going to be given? how do we determine what pka of these compounds are?
What if we are asked to rank the acidity of 5 molecules, with no pka or ka value?
Thank you (Thu 17 dec 2020, 4:52 AM)
How can we determine the pka valueon the basis of( electron donating group) or (electron withdrawing group )?
How do I compare pKa and Ka.. fr example.. I have to see whitch acid is stronger if i have pKa=2,15 and Ka=10^9
Thank you!
Let’s talk about acid stremf.
Still in confusion please make more specific

May you please do some examples on conditional stability constants of EDTA complexes
Wait this isn't pka.. big ups liquid Richard
Do you have an comment on pka value and their bactericidal effect
Thx
Thanks
Wow..I get it...thanx!
what is the pKa of carboxylic acids? Does the pKa of carboxylic acids change depending to what it is bound to?
Guys I need help, please:
Acetic acid is added to water until the ph value reaches 4. What is the total concentration of the added acetic acid?
yup, gotcha

Sir how to calculate ka value? please help
How do you relate pka to pH?
Henderson Hasselbalch equation is the most common relationship.
pH=pKa+log([base]/[acid])
What does pKa stand for?
Pain killer already
how did you get the 10-4 in the part of ka?
