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

Vodno raztopino žveplove kisline bodisi uparite (vodo destilirajte) bodisi poskusite zakisati z vodno raztopino, čemur sledi hlajenje za kristalizacijo, 12 ur pri +1-2 stopinjah je dovolj.
