In order for the salt to immediately precipitate, it is necessary to use anhydrous sulfuric acid, and in solutions with acetone, for example, there can be a 10% concentration of sulfuric acid

Either evaporate an aqueous solution of sulfuric acid (distill away the water), or try to acidify with an aqueous solution followed by cooling for crystallization, 12 hours at +1-2 degrees is enough
