Likewise, the strength of a base is expressed by its basicity constant, Kb. So, the rule is "the stronger the acid, the weaker the conjugate base and vice-versa", which is not exactly the same thing.

This was not well understood for a long time. But the best description uses statistical thermodynamics … Which I will not get into. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. While we say "strong acids dissociate fully in the water" what we really do is we classify those acids that dissociate fully as strong acids - so it is dissociation first, classification as strong later. All systems tend toward the lowest possible energy configuration.

For a student studying Chinese as a second language, is there any practical difference between the radicals 匚 and 匸? I have read that the actual definition of a strong acid is one which will fully dissociate in water, so please do not turn the problem on its head when answering. A common formula used in general chemistry is $\Delta H_\mathrm{rxn} = n(\text{bonds broken}) - n(\text{bonds formed})$. In sequence models, is it possible to have training batches with different timesteps each to reduce the required padding per input sequence? I have read that the actual definition of a strong acid is one which will fully dissociate in water, so please do not turn the problem on its head when answering. weak acids buffer strong bases and vice versa), Confused about weak/strong acids, conjugated acid-base pairs and buffers. Was the theory of special relativity sparked by a dream about cows being electrocuted? Why do strong acids dissociate completely in water? My real question is what is it about the electronic (or otherwise) structure of these compounds, for example $\ce{HCl}$, as opposed to weak acids, e.g. That way more of them can disassociate into solution and actually act as electrolytes. Mmk. Thanks for contributing an answer to Chemistry Stack Exchange! Or that covalent bond strength is directly related to the bond dissociation energy and thus dissociation. Is there a terminology contradiction about whether the conjugate of a strong acid is a “weak base”? Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry. Which acid/base does a strong base/acid react when added to a buffer solution? A little Physical Chemistry: The statement that the products have to have a higher energy than the reactants is exactly backwards, unless something else was meant. Why do I need to turn my crankshaft after installing a timing belt? Is this statement correct: Strong bases will completely dissociate into metal ions and hydroxide ions in solution. $\ce{CH3COOH}$, that makes them more easily dissociated in water. Or am I missing something? I'll save that for a later date. What happens when weak acids and bases dissolve in water … site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. Kb = Kw = 10*-14 (25 ºC). The trick is to consider the medium you are thinking of the dissociation happening in. However, when water dipoles come into account, they change the picture, as they solvate both H. Edit: BTW, the way you asked the question is putting things on the head. It is also my understanding that every acid reaction is in fact reversible (just as with any other reaction) and yet the thing that is different about strong acid forward reactions is that they are shifted so far forward (the equilibrium constant is very high) to the extent that hardly any of the reactants remain after reaction. Just try with "weak" acetic acid (Ka=10*-5); its conjugate base, the acetate ion has a basicity constant Kb= 10*-9. Acids and bases dissolve in water and, because they increase the concentration of one of the products of water self-ionization, either protons or hydroxide ions, they suppress water dissociation. I think it might have something to do with the electronegativity of the ions involved. The strength of an acid is expressed by its acidity constant, Ka. Why `bm` uparrow gives extra white space while `bm` downarrow does not? Borek nailed it.
