Well I am starting to see the connection in some ways. I am going to write something that is probably going to be wrong but want to see what the teacher says.
I did some research and found that phosphorous is a bad thing to advertise because it is bad for people with kidney disease because it may impair absorption of iron , copper which is important for the body.
Phosphate is also bad to advertise because phosphates are naturally occuring in the enviornment and too much of it is bad thing for the aquatic plants. If there are phosphates that go down our drains and into the waterways we cause ecological imbalance.
Now what olly said can come into play in that phosphorous would display a lower percentage compared to phosphate due to their respective molar mass and a lower number will just be better in display.
Any thoughts

?
