[@issifumambelimba8846]

Crystally clear explanations! It does NOT get better than that. We love you for empowering humanity. God Bless.

[@Leah4sciMCAT]

Wow, thank you !

[@tomwolfe1983]

Khan academy needs someone like you

[@Leah4sciMCAT]

Haha thanks, but why? My videos are just as accessible on KZbin :)

[@tomwolfe1983]

Hah, I didn't mean YOU, just that they would benefit from someone who can teach as well as you :) Nice work

[@MedaPeutics]

Dont do Khan Academy! Ugh---some of their teachers talk in circles SERIOUSLY; and KZbin pays :) Stick solo! I love the videos!

How to know ionised to unionised ratio of drugs when pH and pka are given

[@Leah4sciMCAT]

I don't understand your question. For more help with specific scenarios, I recommend joining the MCAT study hall. Full details: join.mcatstudyhall.com/

[@dcsorensen92]

cash money at 8:20 real light bulb moment stuff !

[@dcsorensen92]

more cash at 10:40

[@Leah4sciMCAT]

Glad I could help!

[@anigoldy5038]

How do I calculate Pka if the weak base was diluted and made up to 100 ml while the acid was not?

[@Leah4sciMCAT]

Diluting the base would decrease its concentration. Therefore, you would have to plug in a new concentration for A- in this equation for your diluted base and then, using the pH of the solution that you're given, solve for the pKa in a similar way.

[@anigoldy5038]

@@Leah4sciMCAT Thanks. Does a graph of Pka Vs pH produce straight line graphs?

[@Leah4sciMCAT]

I'm sorry, but I don't offer tutoring over social media. For help with questions like this and more, I recommend joining the MCAT Study Hall. For more details visit join.mcatstudyhall.com/ or contact me through my website leah4sci.com/contact/

[@surat8591]

Thank you!!!!!!

[@Leah4sciMCAT]

You are welcome

[@Idk-bs6in]

Why can't I find one without someone using the Henderson equation, our professor doesn't want us to use it, because one doesn't fully understand what they're doing usually when using it, want the ice table long version

[@Leah4sciMCAT]

I'm sorry you're having trouble finding a video like that for your class, but this video is specifically designed to help students prepare for the MCAT. So I only gave the shortcut. You have to use a regular ICE table for the full version.

Is that a good thing? I hope I was able to help you understand the topic better :)

Sorry you feel that way.

Thank you for your feedback, but I don't understand what you are wanting me to change

Jamirul Hossain are you talking about the captions? Cause you can just get rid of that

[@MoIcasiano]

@@aces985 lol

[@solventbiocide7309]

LOL, a thousand moles of HCl will not fully dissociate in a liter of water. There are 55.5 moles of water in a liter. One thousand moles of HCl will absolutely not fully dissociate in one liter of water. Not enough water molecules to accept that many hydrons. If you are going to make chem vids, you better have it right. LOL

[@Leah4sciMCAT]

Haha that is very true. I went with an extreme hypothetical and never stopped to think about the math

[@johnstillman2935]

thanks know it all , really who cares .

Solvent Biocide lol in all caps isn’t taking the edge off of your comment LOL
