But it is the same topic. I am not shure what is your knowlwdge in chemistry now. Because these are simple neutralsations reactions. But never mind. yeah im sorry, becoz chemistry is not main knowledge and i just want to know what is the reaction, becoz of that i was asking for it. thx for answer btw

These are real numbers. But where come this from? If it meet H+ then it will neutralize the OH groups, perhaps also eleminate the selenite. this was from a journal that search the effect of subtituted HAP by selenite to bioactivity of it. If it meet H+ then it will neutralize the OH groups, perhaps...

substituted HAP reaction
hello, can anybody help me please :3
in this formula Ca10(PO4)5.0(SeO3)1(CO3)zx (OH)2-x , what is the z and x? and what if Ca10(PO4)5.0(SeO3)1(CO3)zx (OH)2-x meet H + ?
thanks for the answer

i meant balance it, thx again mr ChenBeierChenBeier wrote:What do you mean with equalize?
Code: Select all
Ca10(SeO3)9(OH)2 + 20 H+ => 10 Ca 2+ 9 SeO2 + 11 H2O

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...

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. :D :D :D...

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
