# Thread: Chemistry: Demonstrate the definition with a chemical equation for HCl.

1. Demonstrate the definition with a chemical equation for HCl.

HCl(g)+H2O(l)→H3O+(l)+Cl−(aq)

There is an error in your submission. Make sure you have formatted it properly.

That's a rather generic error. I have no idea what it means.
Are there any more details about the error?
And since I'm not familiar with this particular submission system, can you perhaps provide an example of what a similar accepted submission looks like?

Shouldn't it be $H_3O^+$?

5. Possibly an ignorant question: How can you produce $\displaystyle HCl(g)$? I can't see how you can make HCl a vapor. When you boil it don't we just get water vapor coming off? I didn't think that the vapor would contain the HCl?

Hey Dan,

I'm not sure what you're getting at.
According to $HCl(g)$ can be produced by mixing $H_2(g)$ and $Cl_2(g)$ and treating it with UV-light.
And $H_2(g)$ and $Cl_2(g)$ can both be produced by electrolysis of salty water ($NaCl(aq) + H_2O(l)$).
If we boil hydrochloric acid, it'll presumably separate into water vapor and some combination of the gases just mentioned.
