Question

In the equation ..
HCL + NaOH --> H2O + NaCl

would the sodium chloride be aqueous or solid?

Answer 1

It would be in a water solution.

I hope this helps. Thanks for asking.

Answer 2

yeah it did thank you .. so then it would obviously be dissolved in the water, therefor making it aqueous. am i right?

Answer 3

A clarifying note:
The NaOH is a solid and HCl is a gas. They will not react in that state. Most of the time we omit the fact that we use solutions but if we want to do it up brown, we would write
HCl(aq) + NaOH(aq) ==> NaCl(aq) + H2O(l)
Thanks for using Jiskha.

Answer 4

okay thank you and i have another question, what is Barium hydroxide written in formula ? and same with phosphoric acid

Answer 5

actually whats the balanced eqution for barium hydroxide and phosphoric acid ?

Answer 6

Ba(OH)2 + H3PO4 ==> Ba3(PO4)2 + H2O and following the other response I made, generally this would be
3Ba(OH)2(aq) + 2H3PO4(aq) ==> Ba3(PO4)2(s) + 6H2O(l)

More notes: Ba(OH)2 isn't all that soluble but it is soluble enough to make a solution. Too much added to water and it becomes a saturates solution quickly. H3PO4 can be used straight from the bottle as it is a liquid and in solution form as it is sold commercially. But most of the time we use it with some dilution, if for no other reason, to save on chemicals AND it ionizes more freely in solution form. The reaction actually is between the ions in the solution and not between the molecules.

Answer 7

alright thank you
