[edit] Not a complex

If a complex in is a metal coordinated entity, how can phosphate be a complex ion? No metal. The older chemical meaning of the term radical seems appropriate, though. - Dwmyers

[edit] Ecological destruction

...there should be mention of phosphate mining's ecological destruction, especially in small south pacific islands which have been devastated.

[edit] Phosphate expressed as a functional group

Consider adding:

In a phosphate group, a phosphorous atom is bonded to four oxygen atoms; one oxygen is bonded to the carbon skeleton; two oxygens carry negative charges. The phosphate group (—OPO32-) is an ionized form of a phosphoric acid group (—OPO3H2; note the two hydrogens). Organic phosphates, unlike the hydrogenphosphate ion HPO42−, which is the conjugate base of H2PO4−, typically do not express Hydrogen before the Phosphate; —OPO32- reveals that the anterior oxygen is bound to the carbon skeleton.

[edit] Phosphates - The Drink

I was looking for information on the old-timey concoction that they used to call a "phosphate". I'm frankly not sure if there is any actual phosphate in a phosphate (there probably was, as phosphoric acid, to add a "tart" flavor to the drink). I got the following from the "Free Online Dictionary":

3. A soda fountain drink made by blending carbonated water with flavored syrup.

It doesn't mention phosphate as an ingredient, but I found a number of references to Coke and Pepsi as being high in phosphates (read The health effects of drinking soda - quotes from the experts). I also found on this page that "Coke and other soft drinks are acidified with phosphoric acid[...]"

Of course, this goes on the assumption that a "phosphate" was a type of soft drink similar to what we call soft drinks or soda pop today. The only fact that I am sure of is that it was something created at a "soda fountain" (which I believe was also often the local pharmacy). I have a bunch of disparate information, but nothing solid that I could use to update the Phosphate entry or start a new derivation.

I'm hoping this will spark someone with real knowledge to do so.


Some soda fountains of the fifties kept a bottle of "phosphate" near the spot where soft drinks were concocted, and a customer could order, for example, a cherry coke with phosphate. One drop would add some tartness; two drops resulted in a major pucker. Cherry cokes were a prime candidate for this treatment as the cherry flavoring lent an abundance of sweetness. The phosphate, whatever it was, was a clear thin liquid.

NOTE: A phosphate may also be a soda fountain drink, composed of mineral water and a flavored syrup. I suggest to remove this sentence in the lead. From my understanding this article is about the chemical compund, not a soda drink. If that drink is really worth mentioning in any encyclopedia (never heard of it before) it might get its own entry. Any objections? --Splette Image:Happyjoe.jpg Talk 17:27, 31 August 2006 (UTC)

No objection. I'm removing it. =) JohnJohn 19:16, 31 August 2006 (UTC)

While I do not object to that removal, I have heard of phosphate drinks. I have read in several books old folks speaking of buying phosphates at the drug store. Dictionary.com has several definitions that refer to the drink:

a carbonated drink of water and fruit syrup containing a little phosphoric acid.

Basically, it's a soda. Prometheus-X303- 00:21, 4 March 2007 (UTC)

[edit] phosphonate

What's a phosphonate? I know they are something to do with detergents but how (if at all) do they differ from phosphates

a phosphonate is an organic phosphate salt, a phosphate is always an inorganic compound

[edit] Phosphate in foods

Is it really necessary to add phosphates into food?

Depends on your definition of necessary. Is it necessary to have fluffy pancakes, refrigerated biscuits or lunchmeat that doesn't turn into shoe leather? (That's a matter of opinion) Can you substitute it with other nonphosphate compounds that may or may not be as effective or economical? (Possibly)Is it necessary to add it nutritionally? (Probably get enough from a normal diet, but would have to check before stating that as a fact) Sigh NNNs 17:12, 12 September 2007 (UTC)

[edit] Molecular mass

The molecular weight of the phosphate ion (PO4) is, in fact, approximately 94.97 Daltons (30.97 + 16.00 + 16.00 + 16.00 + 16.00) — despite some subtle vandalism to the contrary. Twisted86 06:21, 21 September 2006 (UTC)

[edit] phosphate

what are the top two uses of phosphate? —The preceding unsigned comment was added by 74.244.78.179 (talk) 16:15, August 21, 2007 (UTC)

[edit] Salt

When it is described as a "salt", salt is linked to the page on salt (i.e. sodium chloride). I believe it would be more useful if the page was directed to the chemical definition of salt. k1-UK-Global 20:20, 5 September 2007 (UTC)

[edit] What is Phosphate used for ?

All it says is that it is important in chemistry and biochemistry, but not how or why. Would it be possible for someone to add some examples of where it is used in industry for example ? --Biatch (talk) 01:22, 6 March 2008 (UTC)

[edit] We need coverage of Phosphate as Fertilizer

Under the topic of fertilizer wiki only states that there is a risk of cd or uranium contaimation, we need discussion of the sources and chemistry of phosphate fertilizers and the topic super phoshate. 71.114.181.145 (talk) —Preceding comment was added at 18:09, 9 March 2008 (UTC)

[edit] Phosphate

Refer from Buffering agent, which said: "Buffering agents in humans, functioning in acid-base homeostasis, are extracellular agents (e.g., bicarbonate, ammonia) as well as intracellular agents (including proteins and phosphate)." The important thing is, what kind of phosphate in the cell of human body that work as a buffer? I think this Phosphate article should be expanded to cover that kind of example... Ivan Akira (talk) 10:16, 16 March 2008 (UTC)


Refer from my last talk, I found that the buffering agent from phosphate in the human cell are NaH2PO4- and H2PO4-, please consider this to improve this article. Ivan Akira (talk) 09:06, 17 March 2008 (UTC)
