Buffer Solutions

This chemistry video tutorial explains how to calculate the pH of a buffer solution using the henderson hasselbalch equation. It explains the concept, components, and function of a buffer solution. A buffer solution consist of a weak acid and its conjugate weak base counterpart. It's purpose is to maintain a relatively constant pH value. This video discusses the relationship between the pH and pKa values with the relative amounts of weak acid and weak base components in the buffer solution. This video contains plenty of examples and practice problems.

General Chemistry 2 Final Exam Review:

[ketofitforlife]

Really appreciate you! Our professor is just throwing stuff at us in lecture and homework/quizzes don't line up with the stuff she asks us to read or the lecture. I find myself online for hours trying to figure out what the homework is about. You're a life saver man, I'm burning out over here. 🙏

[junipersily]

this channel saved my high school years and I got 98 on my general chemistry class. now I'm in college and its saving me still. thank you for making these videos! so easy to understand. I'll come back here if I nail my biochemistry.

Edit: I nailed the biochem last semester!!!!

Anyone have a chem final tomorrow and their professor is not good?

[HlomlaMatyeba]

I called a G.O.A.T in Chemistry because of the Organic Chemistry tutor 😅😅❤❤ you are electrifying sir I don't wanna lie. You are the real G.O.A.T 💯 thanks

[july]

these videos honestly help me so much. I have an exam tomorrow and was kinda worried that I wouldn't be able to calculate anything. I just went through the titration video and now this one. Even though english isn't my first language, this was way more understandable than the worksheet my teacher gave us.

in the first 1:20 of the video I was able to understand buffer solutions better than 3 different videos my professor gave me + notes.

Professor Organic Chemistry Tutor, thank you for an exceptional explanation on how to calculate the pH of a buffer solution using the classical Henderson Hasselbalch equation in AP/General Chemistry. Buffers are widely used in both chemistry and biology to maintain constant PH. Many natural systems are also buffered. A buffer has a limited capacity to absorb H+ or OH- Ions. A buffer also has its greatest capacity when the concentrations of weak acid and conjugate base are equal. Hence, to make a buffer, we can choose a weak acid whose Ka is close to the [H+ ] we want. This is an error free video/lecture on YouTube TV with the Organic Chemistry Tutor.

You're a genius. I will never let you and "your efforts" down.🤠

[ayshaghanawi]

Thank you sooo much! I have an exam tomorrow and was so lost about this topic but you explained it very clearly! You are a blessing from God. Wish you all the best

[Mariana-xkbp]

The way you showed the heissen-what’s-it equation 😱 I’m in awe.

[nishadr.]

This is so helpful! I'm starting to understand buffer solutions but it'll definitely take more practice before I get the hang of it. You're also helping me for Cal 2 and I appreciate that.

[busterdies]

I actually love this guy, my professor is both incompetent and rude so trying to learning anything from her or ask questions is a struggle, thank you so much.

[matthewthompson]

Right on time bro, this is what we're working on in class. Thanks for the help as always

[skyedrake]

this mans chronically saving my chem grades i swear he needs a noble peace prize or somethin

[dr.greenvil]

because of you I will probably have a good grade tomorrow. You're videos are the best in the game, thank you.

[taviaiub]

This channel is still saving me in college ❤ thank you for those videos

[salehmigdadi]

Thank you very much professor Im in my 3rd year in pharmacy college and I don’t get well with pharmaceutics but you made it so easy for me to pass the course thank you so much❤️❤️

[brianfugate]

Thank you I’m taking my ap exam today and I now understand these stupid buffers for the first time this year

[jemimadarko]

Julio Gonzales you are a blessing .thank you xx

[fanos]

You are the reason why i got to understand acid base equilibria. 🙏🙏
