Chemistry Forum

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

sorry i think u are misunderstand, my previous post was what is the formula of Ca10(PO4)5.0(SeO3)1(CO3)zx (OH)2-x + H+ =

what is the formula Ca9.5Cu0.5(PO4)6(OH)2 + H+ =
*whatever the H+
thx for the answer

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...

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

Code: Select all

Ca10(SeO3)9(OH)2 +  20 H+ => 10 Ca 2+ 9 SeO2 + 11 H2O

i meant balance it, thx again mr ChenBeier

( Ca10(SeO3)9OH2 )

halo mr ChenBeier

i was tried to equlizer Ca10(SeO3)9OH2 + 11 H{+}, but it seem to imposible to equalizer it. any solution?

thx again mr ChenBeier,

haloo mr chen, i have another problem. based on literature that i have read, the phosphate on HA ( Ca10(PO4)6OH2 ) can be replace 1:1 by selenite SeO3{2-}. and what is it final formula ?


thnks again for answering

oke thx, u such a good man. can i have your curriculum vitae. i want to add u to my citations. if u can u can PM me

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...

Dont think so, it will be simple copper phosphate hydroxide Libethenite http://www.galleries.com/libethenite Cornehite http://www.galleries.com/Cornetite Pseudomalachite http://www.galleries.com/Pseudomalachite thx for answering, im a dentistry student. based on what i read, cu2+ can replace Ca in ...

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
