Phosphorous or phosphate

[Studyinghard]

Suppose you were in charge of an advertising campaign to promote the washing powder. Would you advertise the Percentage of phosphorous or phosphate in the product? Explain

The solutions dont give a good answer. Any one?

[m@tty]

Probably not Phosphorous, as, to me, it brings forth thoughts of Phosphorous grenades. Not the best cleaning solution

[olly_s15]

You would advertise the percentage of phosphorus to make it seem lower due to phosphate having a higher mass, thus higher percentage, hence making the product seem like there is too much phosphorus for the good of the environment.

This is from heinemann isn't it?

yep heinemann. my teacher mentioned something about centrifugation or somethign along those lines. She spoke so quickly i didnt get a chance to get the answer down

Oliver, I don't understand your answer O.o

[simonhu81292]

  i think he is mentioning the percentage composition ...
like the percentage of phosphate would be relatively higher compare to phosphorus as an element in that washing powder

[m@tty]

Phosphate=
as opposed to
Phosphorous=
He is saying not to add the 4 oxygens(~) into the printed percentage.

hm ..still dont see the advantage. isnt phosphorous like in a lot of stuff. like DNA and cell membranes etc so that would be helpful in selling.

matty!!~~~ phosphate has 4 oxygen atoms

phosphorus is just an single element that has 30.97 molar mass...
i am not sure if there is another phosphorus ... lol..   :2funny:

[m@tty]

Doesn't ? ? ? ... fail... :buck2:

[simonhu81292]

ohhhhh matty !!!~~
where have you been?
lol

[superflya]

Doesn't ? ? ? ... fail... :buck2:

id say use a calc

[Studyinghard]

i still need an answer . damnnn this stupid question.

[simonhu81292]

hey.. studying hard .. .what does the anwer say
i was researching and foound "Due to its high reactivity, phosphorus is never found as a free element in nature on Earth"
so therefore it contradicts what the above have said . .
 
also (Phosphorus compounds are also widely used in explosives, nerve agents, friction matches, fireworks, pesticides)
not sure if this helps ... but then as everyone said.. showing the percentage of phosphorus would be way lower compare to showing the percentage of phosphate ....
