Talk:Neutralization (chemistry)

Math-formatted equations
I've removed the following untidy equations from the article and rewritten them in plain code! I'll leave them here in case anyone wants to reinsert them etc.


 * $$Acid + Substance \rightarrow \; Salt + Water : \Delta \;\!\!H = -C < O$$


 * $$Hydrochloric\ acid + Sodium\ hydroxide \rightarrow \; Sodium\ chloride + Water$$
 * $$HCl_{(aq)} + NaOH_{(aq)} \rightarrow \; NaCl_{(aq)} + H_2O_{(l)}$$


 * $$H^+ + Cl^- + Na^+ + OH^- \rightarrow \; Na^+ + Cl^- + H_2O_{(l)}$$


 * $$H^+ + OH^- \rightarrow \; H_2O_{(l)} : \Delta \;\!\!H_r = -55.90\ kJ/mol$$ data 49375988394777398738884749285994

i think im going mad i want to have sex with a hunky man!!!! lol Ben 15:04, 8 August 2006 (UTC).

Does not seem like an encyclopaedic article
I find this article interesting... But strangely incomplete...

The definition is not encyclopaedic at all... —The preceding unsigned comment was added by Milindsmart (talk • contribs) 11:04, 12 February 2007 (UTC).

Merge Chemical neutralization into this article
These two article should be combined. Neutralization has the majority of the information. ChemGardener 02:52, 20 May 2007 (UTC)
 * Done! youngvalter 16:58, 2 June 2007 (UTC)

Need examples.
I think more examples would make it much complete.

universal indicator
i thought universal indicator wasn't used in acid base titrations because it produces a gradual colour change as the solution is neutralised. —Preceding unsigned comment added by Jhendry (talk • contribs) 19:43, 31 October 2007 (UTC) i agree, although i have seen it alkali based in some cases —Preceding unsigned comment added by 86.4.186.147 (talk) 17:55, 24 April 2008 (UTC)

Question
what would happen if you drank enough base to neutralize your stomach? 174.20.135.166 (talk) 23:13, 13 June 2012 (UTC)


 * You'd wind up forming a decent amount of ionic salts, which would probably dissolve in aqueous solution in the water of your stomach contents. The exact nature of the salts would depend on the substance you drank. Although, incidentally, you needn't drink a liquid to achieve this effect. People commonly swallow any of a variety of weakly alkaline substances, like Calcium Carbonate, to neutralize stomach acid. The familiar household pharmacological product, Tums, falls into this category. PhilHudson82 (talk) 06:14, 4 March 2020 (UTC)

complete re-write
The quality of this article was very poor and it contained a lot of irrelevant material. A complete re-write was necessary

I have concentrated on the fact that neutralization is a quantitative process. Each case of strong/weak acid/base is treated separately. The applications section is unchanged. Petergans (talk) 14:10, 10 September 2014 (UTC)

recent edits
I have reverted the edits made by User:Klaus Schmidt-Rohr because they were confusing and did not improve the article. The sssence of neutralization in the context of an acid-base reaction in aqueous solution is that it is a quantitative reaction. Incidentally, ionic charges are omitted from generic species. This is now stated this expliciltly. Specific examples of both acid and base neutralizarion reactions have been added. The text has also been cleaned up. Petergans (talk) 10:58, 27 March 2016 (UTC)

Yes you are right ,its confusing Archit2008 (talk) 07:35, 8 April 2019 (UTC)

Neutralization Equation Structure Theory (NEST)
I have commented this new section out. It appears to be an excercise in stoichiometry. It's all but incomprehensible. A copy is shown below. Petergans (talk) 19:31, 12 April 2016 (UTC)

This theory was first found out by a class 9 student named Sriman Dutta ( also a member of Wikipedia). This theory describes the structure (or format) of an acid-alkali neutralization.

The neutralization equations are reactions between acids and alkalis (bases). Thus, a general acid-alkali neutralization may be represented as

$$(H^+)Y+X(OH^-)\longrightarrow XY+H_2O$$

From analysis, it has been found that there is a relation among the number of molecules of acid reacting with that of the alkali, the number of acid radicals (X) and basic radicals (Y). The general structure of the products side, according to NEST, is $$A(H_NX)+B[Y(OH)_M]$$. So, there may be three conditions which are illustrated below. In general, the neutralization equation is of the following format:
 * When N-B>0, $$A(H_NX)+B[Y(OH)_M]\longrightarrow Y_{[N-(N-B)]}H_{(N-B)}X_M+[{NAB \over M}-(N-B)]H_2O$$
 * When M-A>0, $$A(H_NX)+B[Y(OH)_M]\longrightarrow Y_NOH_{(M-A)}X_{[M-(M-A)]}+[{MAB \over N}-(M-A)]H_2O$$
 * When N-B=M-A, $$A(H_NX)+B[Y(OH)_M]\longrightarrow Y_{BN}X_{AM}+AB H_2O$$

$$A(H_NX)+B[Y(OH)_M]\longrightarrow Y_{[N\pm (N-B)]}H_{(N-B)}OH_{(M-A)}X_{[M\pm (M-A)]}+[{NAB \over M}-(N-B)/[{MAB \over N}-(M-A)/AB H_2O$$

Where / does not denote division, but "or".
