Dear Father Krug, Your towering presence and booming voice have sculpted not just my understanding of chemistry, but my very appreciation for the sciences. Under your tutelage, I've morphed from a mere student into an ardent disciple, eager to absorb every bit of knowledge you impart. Your rugged masculinity and heart of gold blend seamlessly, making you not just a teacher, but a beacon of inspiration. With each dynamic lecture, captivating demonstration, and late-night tutoring session, you, Kruggie, have etched yourself into the fabric of my academic journey. Long live your reign in the realm of academia, for your legacy as King Krug will endure far beyond these classroom walls. Thanks Papa Krugger! Yours in admiration, Hudson

Mr. Krug, thanks for all you have done. I'm only about two hours to your south in TN, and I've been studying your full AP Chemistry playlist along with Princeton Review's AP Chemistry Premium Prep book, and I'm on Unit 3 right now. There are 5 tests in the book, and I'm giving myself practice on the first one. However, the remaining 4 will be used as real tests, so a 5 is obviously my desired score. My high school never offered AP classes, and now I'm going into my third year in college to take General Chemistry I and II, so I figure that going through these with mastery will lead me to steamroll through those courses. I also had a Chemistry teacher so bad in high school that I took nothing away from the course. Chemistry was my least-obtained knowledgeable subject until now. You changed that. It might now be one of my favorites, though I will be a meteorologist. I don't know how true it is, but I head that a score of 100% full marks was attained by only 3 people in the entire world. Even a 72% is sufficient for a 5, which seems lenient. I also plan on taking Organic Chemistry I and II, but I've heard that those courses are the hardest courses in college ever. We shall find out... lol. Great work, man.

@@JeremyKrug Absolutely. Chemistry is a very appealing, amusing, and interesting subject to me. I'm going to be a meteorologist, so chemistry doesn't have that much to do with it, but it's still a very interesting subject to me, so I still plan on taking all the General and Organic courses. I appreciate the outreach, and I'll continue to use your videos as imperative resources.

@@JeremyKrug Hi Mr. Krug! I actually had a video suggestion for you which I think would be exceedingly helpful. Throughout all my practice tests I keep consistently getting questions about lab related chemistry wrong, such as reading burettes, differentiating between volumetric flasks and graduated cylinders, and just writing lab procedures in general. For the 2022 and 2023 FRQs, College Board has been asking students to write lab procedures, so if you could make a video on some important lab procedures and lab equipment, that would be EXTREMELY helpful! Just a suggestion :D. Thank you for your help!

Hi Mr. Krug! Just a quick question (technically 2) - Are your topic videos for AP Chemistry aligned fully with Collegeboard? Like you aren’t missing anything out, right? And I have 7 days to review for the AP test, and I have not anything at all. Please help 🙏

hello sir, i appreciate your videos a lot and they are very useful, though i am a little confused regarding a thing, if the value I write is extremly close to the one on the scoring guideline though is slightly different, am i still getting the point for that question ? (i.e if the scoring guideline accepts 0.035, and 0.036 with decimals carried, do i lose the point for that question if my answer was 0.034 ?).

For % error, is it okay if we switch the correct answer and the calculated answer in the numerator, as long as the denominator stays as the correct answer? I'm worried I might switch up the numbers. I'm thinking that the absolute value would just give the same result.

What we observe in the lab is called the 'endpoint.' If we've chosen an appropriate indicator, we can safely assume the endpoint is very, very close to the equivalence point.

the question on the titration part, it's "the equivalence point", not "the end point".

@JeremyKrug 5 ай бұрын

The question refers to what a chemist sees in an experiment. It is not incorrect to say "endpoint" when referring to what we observe in a titration. In an actual experiment, the chemist observes the endpoint, not the equivalence point. If we have chosen the appropriate indicator, we make the experimental assumption that the endpoint is equal to the equivalence point, and use that for our calculations.
