16.3 The pH Scale and pH Calculations | General Chemistry

[@steffyquint]

Having second semester Gen Chem Exams in a couple of days. Just want you to know that I survived the first semester because of you!

[@ChadsPrep]

Glad you survived - I hope you THRIVE - Happy Studying!

[@hellohowareyou807]

Favorite chem teacher on KZbin! thank you! after sever semesters off from chem courses I am now getting geared up for biochem. Thank you so much!

[@ChadsPrep]

You're welcome and Thank You!

[@soundlessxp787]

Finished my fall semester and just had to come back here after seeing my final exam score-I got a 195/200 on the final, ending the class with an A! I genuinely couldn’t have achieved this without your help. No exaggeration, I watched your videos throughout the whole semester, and they made all the difference. Thank you so much for everything you do, and I wish you the very best! ❤

[@ChadsPrep]

Excellent and Congrats on all your hard work!

[@braedenschedule9825]

Bro, I laughed so hard at the mom joke. Wasn't expecting that. Lmao

[@ChadsPrep]

Glad to hear it!

[@panaiworth6593]

You are an amazing teacher. Thank you for all the help and making things so simple to understand. You are a gem!

[@ChadsPrep]

You're welcome and Thank You!

These videos deserve a like 👍 before they even start!!!

[@ChadsPrep]

Wow - thanks!

[@cheesecakeboy926]

love the your mom joke 😂

[@ChadsPrep]

Excellent!

[@bribrirainbowlove1057]

Righttt😭😭💀

[@AbdulrahmanHashem-o8p]

that was the best your mom joke ever LOL

[@ChadsPrep]

Excellent - my work here is done! 😁😁😁

Glad you think so!

[@NicoleSerra-v3j]

Very helpful! Thank you!!!

[@ChadsPrep]

Glad it was helpful!

[@jfrjr7964]

Thanks. Can you prepare a class on pH calculations from alkalinity equilibrium? CO2, Bicarbonates, and carbonates?

[@Clipaholick]

super helpful, thanks sir!

[@ChadsPrep]

Glad you found it helpful!

[@fgzy123]

I've been watching a lot of your videos lately, thank you. I'm looking for a video that will explain how to calculate the theoretical pH-value for solutions. For example, how to calculate the theoretical pH for a 2.5 mmol/L H2PO4- solution and a 5.0 mmol/L NH4+ solution. There are apparently different formulas based on strong, middle or weak acids, and for strong, middle or weak bases. I'm learning it in a language other than English (Danish), which adds to my confusion since I'm not a native Danish speaker. I'm looking for a good explanation in English. Do you have a video that teaches this? Thanks in advance.

[@kayla7104]

ur the best

[@ChadsPrep]

Thank you

[@jfrjr7964]

I have a question for you. How can we have OH and H in a solution forever and never have a reaction between them? I say forever because you can have steady ph forever in a solution. I would imagine if you put OH- and H+ in a solution it would react quite quickly and neutralize each other to a point where you only have H+ or OH-. And that’s when H,H2CO2, HCO3,CO3,OH concentrations becomes important for PH calculation.

[@ChadsPrep]

Is there a statement in the video that is confusing you here? If so let me know the time. OH- and H+ are in a dynamic equilibrium so there is a constant interaction back and forth between the ions, some react and neutralize and some remain dissociated

[@siril25]

Never noticed anyone menton this in previous videos, but the shirt is amazing!💪🙏

[@ChadsPrep]

Thank you. Happy Studying!

[@zakmatew]

So, at 37C the pH of water is 6.5. Does it mean it is more acidic? Please elaborate.

[@saltymarshmallow918]

7 maybe 7.2.. maybe

[@jfrjr7964]

Calculate yourself. Use Kw for 37C.

[@A23sharon]

yes it is more acidic

[@RelaxRailRide]

Sir, Are you membership acs and iupac?

[@ChadsPrep]

Neither. How about you? Your name implies a fondness for chemistry.

[@RelaxRailRide]

@@ChadsPrep thank you so much sir. Everyday I watching ur videos especially organic chemistry, I love chemistry from my childhood, now doing PhD and my goal is become a scientist. Sir one doubt actually am from India shall I apply for DAT, OR MCAT exams?

[@SANJEEVKUMAR-kn7iq]

Nice video sir,

[@ChadsPrep]

@@SANJEEVKUMAR-kn7iq Thank you.
