Acids, Bases, and pH

Paul Andersen explains pH as the power of hydrogen. He explains how increases in the hydronium ion (or hydrogen ion) concentration can lower the pH and create acids. He also explains how the reverse is true. An analysis of a strong acid and strong base is also included.

I swear in my 12 years of schooling, no one ever told me pH refers to the power of hydrogen.

Soo, halfway into the video and all I can think is,

"I am so fucked for the test tomorrow."

Honestly? my advanced biology teacher assigned this video and I looked at it and was like “absofuckinglutely not” but as I watched it I started to understand more and more about what we are learning in class. I, a 17 year old senior, give this video an A+. it was clear, concise, and it kept my attention. Thank you for your service.

I like how at the end he's like btw the thing that is happening now has happened before and coincides with a mass extinction, anyway bye!

Pay attention kids... U need to know this to grow weed!!

Congratulations, you just explained in a ten minute video what my teachers have been trying (and failing) to explain for two weeks

[carmenmontoya]

Mr. Andersen, you are an awesome teacher.. clear, engaging and mindful to apply the concepts along the way to construct a bigger picture where one not only learns about the components, but also how the parts add up and apply to the bigger picture!  So much more informed and confident in understanding Chem. Excellent teaching! You are a real blessing! Thank you!

Well I am the 1 in 10, 000, 000 that is not going to pass this exam.

GOD BLESS MR ANDERSON!!! IT CLICKED FOR THE FIRST TIME AFTER HEARING MY BIO TEACHER EXPLAIN IT OVER AND OVER AGAIN. THANK YOU

[jenniferaucoin]

This is super helpful. I am taking a college bio class in my late 40s and this was the best video I found online explaining

[tenhorazao]

Best lesson I’ve seen so far! Thank you 🙏🏼 and congrats, of course! You’re one of the bests in REALLY explaining, and that’s cause you REALLY understand hahah

[melisamcdermott]

Ok, so I've been googling this all day to do my homework in biology and this is the first thing I've found that I can understand. I need you as my biology teacher!

[swordpetals]

We're wrapping up our studies on pH, acids, and bases. This has helped me clarify my understanding and go a little more in depth, thanks Paul!

[LoveBud]

I love how he says "I hope that was helpful." Mr. Anderson, you're ALWAYS helpful. Seriously, thank you so much =)

[faridaelbouhi]

I literally want to cry. Years of chemistry classes and I never truly understood what makes acids acidic and bases basic or even what pH is really a measure of. Thank you thank you thank you!!

Hello Mr Anderson, I hope your day is well.
This was an absoloutely awesome video as usual.
You are one of the best at explaining things on here.
Sending lots of love from England. Have a fabulous day

I just learned something that I've been studying for 2wks in a couple of minutes.. Thank u Mr. Anderson....I've been attending my local college for 2yrs now...And my major is Nursing.. When I first started BIO...1yr ago I started watching ur tutorials... Every time I watch, I learn....

[dogeness]

thank you for this, much rather watch a video than read paragraphs on a textbook :p

[lorenzochiereghin]

wow, i'm italian but i understood more than when my italian teachers speak. you're very very good!

"p" is an old mathematical symbol meaning "to the negative log of"
pH=-log[H3O]
