To-do list for Hydroxide: edit Â· history Â· watch Â· refresh

Here are some tasks you can do:

Cleanup: Reorganise the page into more usual headings: Chemical properties, physical properties Expand: Organic hydroxides (properties/uses of quat hydroxides, Hofmann elimination). Use of hydroxide as nucleophile in organic reactions

[edit] Color change

why did (naoh) change his color when we mixed with (hcl)?

From what I remember

NaOH + HCl --> NaCl + H₂O

where both the reactants and products are clear. If you also added [universal indicator] then NaOH would be a blue/purple colour, HCl a yellow/red colour and the products a green colour (if equal amounts of NaOH + HCl used). Hope this helps - Oatzy 21:08 GMT 04/10/05

A Hydroxide is not a ion... OH^- is one --Helios89 10:35, 2 April 2006 (UTC)

well... it depends on how u define the word hydroxide. different people may have different perception of its meaning. in the article, hydroxide refers to the ion containing O and H atoms with a negative charge(OH-). while some of us might have understood it as any alkali substances that have a pH value greater than 7. perhaps "ion" should be added to the title to avoid confusion?

[edit] Joke

 A physics professor and his assistant are working on liberating negatively charged hydroxyl ions, when all of a sudden,
 the assistant says, "Wait, Professor! What if the salicylic acids do not accept the hydroxyl ions?" And the professor
 responds, "That's no hydroxyl ion! That's my wife!"

I don't get it :-( --Slashdevslashtty 02:40, 25 April 2006 (UTC)

I don't get it either...

I get it, and its the worst joke I've ever heard. I'm sad

It's a joke from an early episode of the Cartoon Network cartoon "Dexter's Laboratory". It's not funny, and it's not very original. cobalt91 00:03, 14 September 2006 (UTC)

For those of us who don't get it, will someone please explain! Even if it is bad, I'm the kind of person who wants to know :-( Poobarb 00:33, 3 September 2006 (UTC)

[edit] molar mass

Hey, isn't the molar mass of OH- about 17 g/mol, not 19?? —The preceding unsigned comment was added by Jschwart37 (talk • contribs) 06:53, 4 March 2007 (UTC).

I think the molar mass is still wrong. If hydrogen is approximately 1.01 and oxygen 16 then that makes it 17.01 g mol^-1. Even being more precise (and assuming the pages on oxygen and hydrogen are correct), it must have a mass of a least 17.00734g mol^-1. A minor niggle I know, but these things do affect calculations.78.86.129.231 18:46, 15 October 2007 (UTC)
