The formula Hydroxylapatite is Ca10(PO4)6(OH)2, is it possible to Cu ( Copper ) replace the Ca10? and what is it formula? is it something like this Cu10(PO4)6(OH)2 ?
thx for answering

thx for answering, im a dentistry student. based on what i read, cu2+ can replace Ca in this HA formula ( Ca
10(PO
4)
6(OH)
2 ) in human teeth, what is final formula for that? is it Cu
10(PO
4)
6(OH)
2 ?

Probably only one or two copperions exchange, but I dont think that all calcium will be replaced, because I showed you the copper phosphate hydroxide minerals already. There is not such formulation.
Ca
9Cu(PO
4)
6(OH)
2 or Ca
8Cu
2(PO
4)
6(OH)
2
Otherwise the word Blue tooth will get a new meaning.

whoaaa thx so much, hahaha blue tooth XD
and next question is what if this Ca
8Cu
2(PO
4)
6(OH)
2 meet H+
like Ca
8Cu
2(PO
4)
6(OH)
2 + H+ =

The same what happens before. Decomposition. The copper will be dissolved more easilier because solubilty is better as calcium. Depending of the anion of the acid.

i dont know formula of the acid, but its say the acid from peat swarm water is humic acid and fulvic acid
what if just H+, sorry i cant remember redox reaction from school. can u equilibrium it. thx again

hey i just found out this Ca
8Cu
2(PO
4)
6(OH)
2 + 8 H
+ = 8 Ca
2+ + 2 Cu
2+ + 6 (HPO
4)
2- + 2 H
2O. is this correct ?

haloo mr chen, i have another problem. based on literature that i have read, the phosphate on HA ( Ca
10(PO
4)
6OH
2 ) can be replace 1:1 by selenite SeO
32-. and what is it final formula ?
thnks again for answering

2 PO4 3- are equal to 3 SeO3 2-
Mathematics
( Ca10(SeO3)9(OH)2 )

halo mr ChenBeier
i was tried to equlizer Ca
10(SeO
3)
9OH
2 + 11 H
+, but it seem to imposible to equalizer it. any solution?

What do you mean with equalize?
Code: Select all
Ca10(SeO3)9(OH)2 + 20 H+ => 10 Ca 2+ 9 SeO2 + 11 H2O
