It is a forum rule that you must attempt to answer a question before we can help you.  What do you think might happen?

oh, thx for clarifying.

I would asume it disloves over time into hydronium, chloride (that will to some extend evaporize, but also bound with Na to from NaCl) and water.

I don't see any chemical bond sensitive to sunlight here. Is there one?
Dissolved HCl ionizes unless it's very concentrated, and needs no light for that.
Water will evaporate if the brine and the acid aren't very concentrated from the beginning.
Hydrogen chloride too evaporates slowly to form a fog with air moisture.
