Write out the balanced equation for the reaction that occurs when Ca(OH)2 and H3PO4 react together.

Question

anonymous · Answer

I am working on my answer but I'm pretty sure it'll have a mistake. /i'll post when finished.

anonymous · Answer

So before balancing , it's 
 $$Ca (OH) _{2} + H _{3} PO _{4} ---> Ca _{3} PO _{4}^{2} + H OH _{2}$$

anonymous · Answer

Yes? Maybe?

australopithecus · Answer

No,
Ca has a charge of 2+
PO4 has a charge of -3

so you will get:

Ca3(PO4)2 + H2O

Hydronium ion is not stable at all

Furthermore this is a bronsted acid base reaction thus one of the products will always be water

3*2 = 6

anonymous · Answer

I don't understand the switching from H OH2 to H2O. I understand the concept but I dn't understand how it doesn't mess up the subscripts.

australopithecus · Answer

You are reacting an acid and a base you will get H2O and a neutral compound

H3O is highly acidic
