Talk:Equivalence point

Grammatical mess

First sentence is a grammatical mess. —Preceding unsigned comment added by 128.62.52.74 (talk) 03:45, 13 April 2011 (UTC)

Removed statement "Most of the time the equivalence point is at a pH of 7 and 50 mL of NaOH"

not all titrations are acid base.

Yes, what he said. Acid-base may be a good example though. I have reorganized this article, using acid-base as an example and giving an accurate definition. This was a quick patch job though.

Yep, what you guys said. A good example to build in would be the redox titration of hydrogen peroxide with potassium permanganate. No acid/base and no indicator present.

If you have equal ammounts of hydroium and hydroxide how can the ph not be 7?

Where did the above statement come from? I don't see where that is suggested. It is quite possible to mix equal volumetric, mass, or molar amounts of an acid and base and not have a pH of 7. - nick

The statement came from an anonymous editor - check the page history if you are unsure. All comments should be signed with four tildes, including your own if you don't mind. Now as for not having a pH of 7, this occurs when one species present (e.g. CHCO₂^-) is acidic or basic. Richard001 21:21, 5 June 2007 (UTC)

They are not identical, but an endpoint is a form of equivalence point, so they should definitely be merged. Agreed? Richard001 21:21, 5 June 2007 (UTC)

Per our discussions elsewhere, yes.Bless sins 11:31, 6 June 2007 (UTC)

That's good enough for me. I don't have any time right now but if someone wants to move everything they can into this article please go ahead and do so. Richard001 11:51, 6 June 2007 (UTC)

A level chemistry states that an Endpoint is NOT an equivolence point. —Preceding unsigned comment added by 86.143.136.18 (talk) 18:07, 8 October 2007 (UTC)

They are NOT the same thing and often students are asked to explain the difference. I've included proper use of endpoint in the article, see the titration article for a better contrast. Fairywren (talk) 03:51, 18 September 2008 (UTC)

Endpoint and equivalence point are absolutely not the same - endpoint should not redirect to equivalence point. The equivalence point of a strong acid-strong base reaction is always pH=7, but the endpoint does not share this constraint.Kinetochore (talk) 01:43, 13 April 2009 (UTC)
