16.2 Introduction to the pH Scale and pH Calculations

[@alyssaramirez9880]

These lectures are a godsend now that my class is online. Thank you for these! They are a better format for me in the way in which they are presented than the current platform my university has switched to. And Chad, thank you for breaking everything down in a clear and understandable way!

Love to hear it Alyssa! Glad any of this is helpful, particularly in these times. What a blessing youtube is during all of this. Keep at it and stay healthy!😀

Chad you made me like general chemistry which is a miracle. I hated it before due to the vibes I would feel with teachers teaching it to me. It goes to show you that sometimes when we say we don't like a subject or we are bad at a subject is not entirely true. It is not the subject that we didn't like or that we are bad at it, it is just the teaching style we received that we didn't like.

Very true R Ramirez. I used to poll incoming freshman and ask them about their high school chemistry experience, simply whether they would describe it as good or bad. For classes of chemistry majors roughly 75% would claim they had a good experience. For classes of non-chemistry majors only 25% would claim they had a good experience. Here, a student's high school chemistry course/teacher had a significant impact on whether they were pursuing a career in chemistry or not. Ultimately, lots of pressure on educators. Best in your studies! :)

@@ChadsPrep Chad, that was very insightful what you just shared. I wish I had teachers like you when I was younger, it would have saved me a lot of trouble. I have a 3 month old baby and I am going to be very careful with how his education is given when he gets older. It saddens me how many past brilliant students that are not currently in STEM but could have contributed immensely in the sciences if they had a teacher like you. I could say you are one of the few teachers that is EXTREMELY talented in teaching many different types of students. You are doing a great service to many students all across the world and I don't know if you are told that as much. Thank you for your videos. There is this quote "One child, one teacher, one book, one pen can change the world". And I think you have done that more than what you think by helping students become professionals all around the world with this videos. lol Take care!

You've discovered my secret!😁😁😁

Ah man now that I know about that 31x business that gives me a whole new perspective on thinking of the 9.0 Cascadia Subduction earthquake that's overdue 😮 I knew Richter was logarithmic but I didn't know it was not base ten!

[@SaketRamCoolPolar]

Is -log[H+] same as -log[H3O+] because the slightly negative Oxygen atom attracts the lone Hydrogen atoms (IMFs)? Just want to make sure😅

[@ChadsPrep]

H+ and H3O+ are synonymous. H+ is commonly referred to as a "naked proton." But they're so reactive that in aqueous solution they combine with water to form H3O+. So we treat them as synonymous for aqueous solutions. It actually turns out that most of the time each H+ will actually complex with multiple water molecules so even referring to them as H3O+ is 100% accurate, but it is our accepted convention. Hope this helps!

Chad's Prep Thank you for the clarification!
