### HCl Acid

In lecture we discussed how HCl in an aqueous state is hydrochloric acid. So, if we do not specify that HCl is aqueous, is it not considered an acid?

If HCl is not specified as aqueous, it is in its solid, powdered form, where it is not considered an acid.

I feel that in the Bronsted definition, it did not specify that the acid/base must be in aqueous form, as the definition of acid if "a substance that can donate a proton to another substance". So the important thing is that it can donate a proton.

### Re: HCl Acid

Most acids must be aqueous as this implies the idea that the acid can dissociate when in solution. This follows the Arrhenius definition of an acid, as this definition basically means that the acid will dissociate into its conjugate base along with an H+ ion.

I realized I kind of didn't answer the question, my bad ahhhhh
If the state of HCL is not mentioned, then depending on the context of the reaction you can see what state it is. For example, if it is reacting with water to form hydronium ions and chloride ions, then it is most likely acting as an acid and is aqueous.
