This acids and bases chemistry video provides a basic introduction into acid strength and base strength. It explains how to determine which acid is stronger given the Ka and PKa values of the acid. It also explains how to determine which acid is stronger by considering factors such as size, electronegativity, and stabilization of the conjugate base. In addition, it mentions how to determine which conjugate base is stronger based on the Ka of the conjugate acid. This video contains plenty of examples and practice problems.

There are certain trends for H-X acids with X being a very electronegative element, as well as H-O-X acids and H-(n)*O-X acids you just gotta memorize

@alexp2019 4 года назад

Rick F lol, that’s not chemistry, it should compare stability and electronegativity

@yourboy9236 4 года назад

@@alexp2019 yeah that's what he's talking about in terms of trends

@princesspat5239 3 года назад

well, u remember the strong acids and the strong bases, then you know also bases and acids that have zero strength. The rest are weak acids, or base and to find out which one is a base or an acid: see which one gives protons and receive protons.

amazing video, if I keep grinding this sem I should finish w a perfect 4.0 for 2nd sem in a row or worst comes to worst 3.92 overall, ur videos and chads prep are saving me so much thank you from a future dentist, ur a great human god bless

@abhishree5861 6 лет назад

Heyy this is a great video! Although I have a question. What if we aren't given a Ka value for the first question. Is there a way to identify which acid is stronger?

Hello tutor, I can't begin to explain you how much your videos are helpfull, so thank you ! I just had a request, could you summarise all the concepts you overviewd at the end of each vidéo, just to Make it clearer and give us a structure. Thank you in advance. #belgium

@skdkcidiwsixi 2 года назад

1:50: important detail about oxy acids is that you need to look at the unprotonized O-Atoms in the molecule, so the actual number to estimate the Ka value is [number of O-Atoms in the molecule] - [number of H-Atoms in the molecule] also you can roughly calculate the Ka value just by that number. just multiply the number of unprotonized O-atoms by 5 and subtract it from 8.

I managed to get the first 8 questions correct. 8:01 True for *inorganic* acids; organic derivatives of these acids can also be strong, such as methanesulphonic acid.

@nataliakesto3734 3 года назад

for HIO and HBrO wouldnt the stronger acid still be HIO because the hydrogen is technically attached to the I not the oxygen??

Why Hf is the weakest acid ??

@lisaa23581 3 года назад

Because it's the toppest on a group so it's size will be small as compared to HCl, HBr, HI. It will be strongly bond to the hydrogen atom and thus it will not loose it's H+ easily which makes it a weak acid. Those below the group have weak overlaps because of large size of the X atom so they'll loose their H+ easily making them a strong acid.

@worshipsonglyrics5861 10 месяцев назад

I have a question. For binary acid, I understand the strength is based on the size of an ion due to its stability. However, the size of an ion decreases as we move the periodic table from left to right, which contradicts the concept of ion stability. Can somebody clarify this?

What if I have to rate from strongest to weakest, but I have HCl, H2SO4, HBr, HNO3, CH3COOH? How do the trends work if I have both acid with and without O

which acid is stronger sulfuric acid or Nitric acid

@niladritachakraborty5273 6 лет назад

What is the reason behind 6th question? Becoz I know HF is stronger than HCl due to it's high electronegativity

@BledWh1te 6 лет назад

It's actually the opposite. HCl is one of the strong acids, HF isn't. The high electronegativity of fluoride holds on to the hydrogen more strongly, so that proton is less likely to dissociate -> its a weaker acid

@nkchamplin 6 лет назад

I agree with BledWh1te. The strength of the acid could also be determined qualitatively by considering the relative stability of their respective conjugate bases. Using this perspective, HCl would be considered a stronger acid because Cl- would be more stable than F-. In this case, the larger the atom the more volume available to disperse the negative charge. This trend continues down the same period. F- < Cl- < Br- < I-. Hope this helps!

@dimkacracker 6 лет назад

Cl is bigger than F so the bond between Cl-H is longer than the bond between F-H, and we know the longer the bond the weaker the bond so Cl lets go of it's Hydrogen much easier, and acidity is how readily an atom gives up its proton.

@lightning8675 5 лет назад

Higher electronegativity only wins when going across a row (moving left to right). But when in the same column/group, electronegativity doesn't win, atomic size does. So going down a group/column means greater acidity despite electronegativity becoming smaller. Reason: bigger atom=more surface area=spreads out negative charge better=more stable=more okay with letting go of that hydrogen.

If the weaker living are destroyed and vanished, what good and bad values go vanish with them. If we have the forced will to destroy the weak, we find a good reason. We had less emotional intelligence. Or i couldnt stand her dumb mind. Did she have got any strong values. She was dumb. In a good way. She saw equality in all living. She was good, best, bad and worst in the same person. She saw herself in all living. She was a weaker person. She was a living in this world, where all living are the same.
