Talk:Acid–base reaction

message: Should we throw in the Drago-Wayland equation for the enthalpy change in Lewis acid-base reaction or should it only go to Lewis acid's own page? I don't know any more about it than what I just googled up. It seems to be fairly modern. Cubbi 04:29, 11 April 2007 (UTC)
replies: text: Lewis acid-base reaction deserves it's own page, really, because expanding into the whole frontier orbitals-land, and all that will make the section become disproportionately big, maybe? I'd prefer to make the article Acid-base reaction because the theories aren't all that are involved :-)   ♥♥ ΜÏΠЄSΓRΘΠ€ ♥♥ slurp me! 08:10, 11 April 2007 (UTC)

message: I've searched google, my books, historical books, and even ones with in-depth information about Lux-Flood, and almost zero is known about them. Any chance someone would want to mount an original research project if they live in germany?   ♥♥ ΜÏΠЄSΓRΘΠ€ ♥♥ slurp me! 23:20, 13 April 2007 (UTC)
replies: text: Actually, Flood is Norwegian. I made a link cause I wanted to make a stub about him from random tidbits that google shows to his full name and to "Professor Flood" and stuff. Cubbi 02:15, 14 April 2007 (UTC)
replies: text: Done. Check out Hermann Lux and much less impressive Håkon Flood (and yes, they both need work) Cubbi 05:41, 14 April 2007 (UTC)

text: Hey, I think the page should have something detailing what happens when an acid and a base react, or the article is sorta pointless.(Freddy Lu (talk) 22:10, 17 January 2009 (UTC)
thread_title: Hermann Lux and Håkon Flood.. unsung ghosts of Chemistry?

message: I am not sure "Acid-base reaction" would be the right name for this. The content, as it is right now, describes empirical and theoretical answers to "what is an acid" and "what is a base" with examples of how some reactions may be described with those answers. FWIW, check out the names of this article in other languages - it is "Theories of Acidity and Basicity" in SR and SU, "Concepts of Acids and Bases" in DE, and "Acid-Base Reactions" in IT and EL. I am not sure what's better for English as I've never read a Chemistry textbook in English :) Cubbi 21:03, 15 April 2007 (UTC)
replies: text: Hmm, i was just attempting to try and pick the most "accessible" name for this, rather than something more accurate but less-accessible. Again, just because it may be more accurate to talk about a sub-field, acid-base chemistry is generally pretty large -- Acid-base reaction redirects here anyway, and the name "theories" means that we are technically limited to only discussing the theories of acid-base reactions and not the underlying principles. Generally, an article that ends with "s" is plural, which is generally not used on the wikipedia.. i imagine there is "Reactions" in IT/EL maybe because of grammatical structure of Italian.. i'm unsure. Still, maybe "Acid-base chemistry".. but i couldn't think of any others that were general enough.   ♥♥ ΜÏΠЄSΓRΘΠ€ ♥♥ slurp me! 06:16, 16 April 2007 (UTC)
replies: text: "Chemistry" sounds good to me, actually. Cubbi 14:17, 16 April 2007 (UTC)

text: Anyone new to chemistry wanting to know how an acid and a base react with each other would probably end up here instead of the neutralization article. He or she would read the first sentence An acid–base reaction is a chemical reaction that occurs between an acid and a base. And after that, ... ?? Lost!

message: In my opinion there is absolutely no way the external link "Acid-Base Tutorial" should be there. It is not an Acid Base Tutorial as one expects. Its "major feature" is an applet that has nothing to do with the basics of Acid-base reactions.
Someone who has more involvement with this webpage then me should remove it or relabel it. Dave3457 (talk) 00:51, 17 February 2009 (UTC)
replies: text: Good point. Someone must have added it because of the seemingly fitting domain name (acid-base.com) but it's really a simple web page about pCO2 and pH in humans, which this article does not talk about. Gone. --Cubbi (talk) 04:37, 17 February 2009 (UTC)

message: The naming of this article confuses me. See this redirect. Why does this use a long dash instead of just using the minus sign as a dash as is common? Tyciol (talk) 14:47, 13 March 2009 (UTC)
replies: text: Using the dash is wrong in terms of typography, I suggest it is renamed to contain a hyphen (that is probably what you mean by "minus sign"). --Nefronus (talk) 17:18, 16 June 2013 (UTC)

message: Is there an article about all that stuff people talk about certain foods being acidic or basic depending on their nutrients or effect on the body? Like usually they say meat is acidic and that lemon juice, despite having acids, is basic due to effect on the body. I don't really understand it but an article exploring this recurring idea would be valid to link to. Tyciol (talk) 14:47, 13 March 2009 (UTC)
thread_title: Acidic and basic food

message: Here's a quote from the article: "he was not aware of the true composition of the hydrohalic acids (HF, HCl, HBr (hydrogen fluroide), and HI) (hydrogen iodide)". As far as I can see, the 'fluroide' mentioned is the result of a simple spelling error (it should be fluoride) and the parenthesis is misplaced, because HF is hydrogen fluoride and HBr is hydrogen bromide. The second thing is, why write out hydrogen fluoride in a parenthesis but not also the other two compounds? They all have links and it seems inconsistent. I'd prefer writing out either all compounds, including hydrogen iodide, in the same paranthesis - placed after hydrogen iodide, or none of them. Thirdly, the parenthesis placed just after HI is misplaced and should be put after the current last parenthesis of that sentence. The reason I haven't done these changes myself already is that I haven't edited much and I'm afraid to make a mistake and mess up a link. Knowledgelover121 (talk) 08:09, 1 December 2010 (UTC)
replies: text: OK, I have deleted the names as unnecessary here. Anyone who doesn't know what HF etc are can click on the links. Dirac66 (talk) 16:56, 10 December 2010 (UTC)
thread_title: A couple of proposals

message: In highly-polar molecules, such as boron trifluoride (BF3), the most electronegative element pulls electrons towards its own orbitals, providing a more positive charge on the less-electronegative element and a difference in its electronic structure due to the axial or equatorial orbiting positions of its electrons, causing repulsive effects from lone pair – bonding pair (Lp–Bp) interactions between bonded atoms in excess of those already provided by bonding pair – bonding pair (Bp–Bp) interactions.
Hard to read for a chemistry newcomer. The previous sentence is also heavy.

replies: text: Much improved. Except that you used B for Base 4 times and B for Boron 3 times in the same paragraph, which could confuse a reader. I have changed B for Base to D for Donor. At least there is no Deuterium in this article. Dirac66 (talk) 11:16, 29 September 2014 (UTC)
thread_title:  Complicated sentence 

message: I have found no defintions of Ka defined as
Ka= [HA]/([A-][H+])
but have seen multiple references including the first page of this article defining Ka as
Ka = ([A-][H+])/[HA]
This is the definition in common use.   
It follows then that the expression in the article should be
[AH]Ka1 = [A-][H+]  not [AH]=Ka1[A-][H+]
the subsequent 2 formula are affected.
So there is either an algebra error in this article or am I missing some greater context.

replies: text: Yes, you are correct. Thank you for noticing this. I will fix the article. Dirac66 (talk) 02:04, 24 January 2016 (UTC)
thread_title: Formula Error

message: The wording for the definition of an Arrhenius acid/base is confusing and contradictory.
In part it states that:
"an Arrhenius acid is a substance that dissociates in water to form hydrogen ions (H+);"
"an Arrhenius base is a substance that dissociates in water to form hydroxide (OH−) ions;"
This matches my understanding of an Arrhenius acid/base, as this indicates it must contain a hydrogen which leaves to become "H+" to be an acid, or must contain hydroxide which leaves to become OH- to be a base.
But later on, the page states:
"Overall, to qualify as an Arrhenius acid, upon the introduction to water, the chemical must either cause, directly or otherwise:
an increase in the aqueous hydronium concentration, or
a decrease in the aqueous hydroxide concentration.
Conversely, to qualify as an Arrhenius base, upon the introduction to water, the chemical must either cause, directly or otherwise:
a decrease in the aqueous hydronium concentration, or
an increase in the aqueous hydroxide concentration."
This instead indicates that anything that increase the H3O+ concentration is an Arrhenius acid, and anything which increases the OH- concentration is an Arrhenius base.
If you consider something like FeCl3, it doesn't contain a hydrogen atom and can't dissociate to form hydronium ions. So the first definition excludes it.
However, if you put it in water, it will cause an increase in the hydronium concentration. So the latter definition indicates it should be an Arrhenius acid.
Likewise, carbonate/bicarbonate, and ammonia are all examples of bases which do not have the required hydroxide, so are excluded by the first definition of a base; but do still increase the hydroxide concentration and would be included by the second definition.
The iron chloride example also causes issues for grouping all Arrhenius acids under Bronsted-Lowry acids.
I assume the first definition is correct, and the latter one is wrong; but I don't have the original source to confirm, and find conflicting information online.

replies: text: if there are reliable sources for both (and even sources admitting that conflicting definitions exist, as this Khan academy course does, with "depending on your class—or textbook or teacher—non-hydroxide-containing bases may or may not be classified as Arrhenius bases." ), we should document that as such. --Cubbi (talk) 02:23, 29 March 2022 (UTC)
