On Giwers chemistry, Giwer Matt

Matt, As I said yesterday, I am new here, so forgive my asking, what on earth is all
this about???

Chemist? CHEMIST??? You are kidding us? Calcium peroxide in bone ash from bones
reduced to ash? CaO3??? Do you have some handy? I have never seen nor heard of a calcium
ozonide or whatever this stuff would be, but I assure you that neither compound would
last long at high temperatures in a reducing environment, such as a charring bone! And
as for burning the stuff… You ARE kidding us surely???

And why do you think that such ash would not be a fertiliser? OK, OK, it would be a good
idea to let it cool down a bit first, but most soils are poor in phosphates and bone ash
has been used as fertiliser for yonks. (Hmmm, actually I admit that maybe it has not
been used lately, because it is cheaper to use phosphate rock and bone meal is too
valuable as an animal feed, but it certainly used to be used and in a poor, acidic soil
it was great stuff. What would you expect? Why should it not be? Do you imagine that
PO4-3 loses its nutritive value just because it has been filtered through a poet or a
housewife before being released by cremation? There may be better sources and kinder
ways of obtaining the stuff, but that does not change the chemistry and I thought this
was the chem forum.

Please don’t do us any favours. Learn a bit of chem first. It is far better at keeping
you from making a fool of yourself than amy amount of recitation or shouting “yer
muvver’s another!”

Chemical fact. Trust me. I’m not a doctor.

Cheers

Jon

Mr. Giwer’s confusion is due to the fact that he has no clue about
redox chemistry. I explained to him that the calcium was in its +2
oxidation state. Mr. Giwer apparently thought that must mean that
calcium has 3 oxygens. When I corrected him, he thought I must be
saying that it has two oxygens.

Mr. Giwer, for your edification:

The oxidation state refers to the formal charge carried by an atom in a
compound. Calcium metal has an oxidation number of 0: it has no formal
charge. In almost every naturally occurring compound conceivable
calcium is in its +2 oxidation state: it has a formal charge of +2.

Thus Ca3(PO4)2 can be thought of as three Ca++ ions and two PO4—
ions for a toatl charge of 3(+2) + 2(-3) = 0.

Calcium oxide is CaO and NOT CaO2 or CaO3. Oxygen almost always has a
formal charge of -2. Thus Ca(+2)O(-2) is neutral.

There exists a superoxide anion O2–; so CaO2 is in some sense
conceivable, but I’d be very surprised if you found it anywhere in
nature. CaO3 is a joke.

The only claim I have made about bone is that calcium is in its +2
oxidation state, i.e. it has a formal charge of +2. Dr. Bilik posted
some information about the composition of bone that, of course,
confirmed this. Mr. Van Alstine posted information about bone ash that
also confirms this.

The only thing that this proves is that Matt Giwer does not have any
familiarity with basic chemistry.
