Substitution reaction
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

Dont think so, it will be simple copper phosphate hydroxide

thx for answering, im a dentistry student. based on what i read, cu2+ can replace Ca in this HA formula ( Ca10(PO4)6(OH)2 ) in human teeth, what is final formula for that? is it Cu10(PO4)6(OH)2 ?ChenBeier wrote:Dont think so, it will be simple copper phosphate hydroxide

whoaaa thx so much, hahaha blue tooth XDChenBeier wrote: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.
Ca9Cu(PO4)6(OH)2 or Ca8Cu2(PO4)6(OH)2
Otherwise the word Blue tooth will get a new meaning.
and next question is what if this Ca8Cu2(PO4)6(OH)2 meet H+
like Ca8Cu2(PO4)6(OH)2 + H+ =
i dont know formula of the acid, but its say the acid from peat swarm water is humic acid and fulvic acidChenBeier wrote: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.
what if just H+, sorry i cant remember redox reaction from school. can u equilibrium it. thx again
hey i just found out this Ca8Cu2(PO4)6(OH)2 + 8 H+ = 8 Ca2+ + 2 Cu2+ + 6 (HPO4)2- + 2 H2O. is this correct ?JinoJi wrote:i dont know formula of the acid, but its say the acid from peat swarm water is humic acid and fulvic acidChenBeier wrote:The same what happens before.

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