pH, pOH, H3O+, OH-, Kw, Ka, Kb, pKa, and pKb Basic Calculations -Acids and Bases Chemistry Problems

This acids and bases chemistry video tutorial provides a basic introduction into the calculation of the pH and pOH of a solution. This video explains how to the calculate the hydronium ion [H3O+] and the hydroxide ion [OH-] concentration given the pH or the pOH of the solution. This video contains the formulas and equations needed to calculate Ka and Kb using Kw as well as the pKa and pKb of acids and bases. This lesson contains plenty of examples and practice problems.

The man, the myth, the legend. You’re the reason I just got a 78% on my Chem exam and now I have a high B+ in Chem. I’m also passing Calc 2 thanks to you. Do you realize how many students lives you are saving? I want to personally thank you from the bottom of my heart. You deserve the world and more.

[riccilibron]

I don't even skip the advertisements anymore. You taught me more than my teacher, bro.

[selalorin]

Man this helped a lot. Is it bad that i learned this the day of my test? 😂

[yailinmakelifelovelier]

13minutes with you > than 3 weeks of classes +/= success in chemistry test^2
I appreciate your videos a lot. Thank you very much.

00:00 What is the pH of the solution if the (H30+) concentraion is 2.5 * 10-4 mol/L?
1:55 The pOH of the soultion is 4.5. Calculate the pH of the solution
3:37 If the pOH is 3.8, what is the (OH-) concentration?
5:12 What is the pOH of the solution if the (H3O+) concentration is 4.2 * 10-3 mol/L?
6:24 If the Ka of an acid is 1.8 * 10-5, calculate the pKa and pKb values of the acid.
7:52 If (H3o+) = 7.1 * 10-2 mol/L, calculate the (OH-) concentration
10:08 If the pKa of an acid is 3.7, what is the Kb value of the acid?
10:57 Calculate the pH of a solution if the (OH-) concentration is 0.015 mol/L

You are the best thing YouTube has to offer. This channel & your great work deserves way more credit.
Thank you for doing what you do, Sir.

I JUST WANNA SHARE THAT IN 2018 I WATCHED THIS VIDEO JUST MINS. BEFORE MY LONG QUIZ IN CHEMISTRY AND I WAS THE ONLY ONE IN THE ENTIRE BATCH WHO GOT A PERFECT SCORE (actually went over! 27/25) SO THANK YOU ORGANIC CHEM TUTOR

Edit: LOL it's 2023 now; I forgot I commented this. Thanks for the likes, guys 😅. Some people seem to not believe me HAHAHA but this was true! I was able to get a perfect score because, to my luck, the test focused on this video's topic. And there was a bonus ques for 2 points, which surprisingly I remem 😂 It was "Sodium hydroxide is also called what?" And I answered lye :)

[AltairAC]

Honestly, I'm speechless. I not only look up to you but I admire you because of how simply you can explain such a difficult to understand topic. Its honestly astonishing how you can summarize week long lessons in a 13 minute video and deliver it in a format that is easy to comprehend. Not only did you teach me this topic, but you also guided me in learning and understanding every other difficult chemistry-related topic. It absolutely amazes me how much you do for the people who watch you. You have my thanks.

[fainatoole]

This man has gotten me through my entire Cell Biology and Neuroscience degree and now I am on my MCAT grind and he is saving my butt yet again. Thank you for saving me so many times over many years. Your videos are amazing!!!

[jessicafanfan]

Thank you for this! My professor is getting paid for no reason!

[dovebun]

How I wish I can like this hundred thousand times

[estherng]

wow! I was so pissed off that I couldn't get this chapter a while ago, now I feel like I can see the light! Thank you

[bumboomie]

Thank you so much! I've been having a hard time following my professor's lectures due to online classes having limitations and such. And the fact that I'm really bad with computations, this really helped me a lot! Much thanks from a freshman!!

[sg]

Thank you so much for saving my chemistry grade. Simple, well explained and to the point. Please keep making content like this, you're helping so many students. Thanks 10000 times over!

[Raxacoricofallapatorius]

Absolute legend, thanks man!

My lecturer quite literally barely explained how to do any of this and just expected we'd already know it or that we wouldn't need help figuring it out on the little info he did give. So thanks again.

[pennywood]

My Chem 107 Class moves so quickly I barely can keep up with Lecture notes. However, watching your videos are truly a life saver, the way you break it down, review each any every step not to mention cover questions that I didn't know I had. Thank you so much I would not be making it through this class without these videos.

[zazopink]

wow you truly are living up to your purpose! The way you help others is amazing and I hope your getting paid in money and in joy because of it.

[mustindoesgaming]

This guy is single handedly saving me from completely flopping my chemistry final

[vianneysean]

I freaking Love you.! You are the best teacher EVER. Straight to the point and simple.! 👍

[tristanallain]

I have understood everything so much better when it comes to chemistry, calculus, physics, etc because of this Chad.

This man deserves some sort of award for all the hard work hes put into his channel and how much hes helped us all.
