Rechristalization Separate the Dissolved Solids from Aqueous Solution

I have a liquid mixture in a bottle containing different synthetic substances dissolved from their salt forms (i.e. lidocaine hydrochloride, anhydrous caffeine). These compounds are dissolved in distilled water.
So the question is: How can I separate the dissolved solids from the aqueous solution? Can I do it by forming a hydrochloride precipitate by adding some hydrochloric acid? Or, say the sulfate salt by adding sulfuric acid, etc.?
Thanks in advance

Crystalization or LLE should work..
There is something called as common ion effect. I think that acid addition is something to do with shifting the equilibrium. Sometimes in LLE the pH change (addition of acid) helps in adjusting solubility coefficient.
