    it is precipitation read more at http://en.wikipedia.org/wiki/Precipitation_(chemistry)

    becasue i think it's one of these three: evaporation/crystallixation , distillation or chromatography

    if it's a multiple choice question then I would choose crystalization if not I'm sure it's precipitation because crystalization is a form of precipitation . "Crystallization is the (natural or artificial) process of formation of solid crystals precipitating from a solution, melt or more rarely deposited directly from a gas." this is wikipedia's definition of crystallization, the rest are a specific way of extracting a substance from solution , precipitation is a more general notation.

    no it's not a multiple choice question.

    if the solid is soluble, you won't have much luck forming a precipitate, but i'd try evaporating the solvent.

    Evaporation is used to extract 'stable' solute from solvent. So basically, the solution is heated and evaporated, leaving solute behind. Crystalisation is used to extract 'unstable' solute from solvent. Unstable solute will decompose into other substances upon too much heat. Hence, the solution is heated until saturation point (about 1/3 of the original content). Then, the saturated solution is left to cool. Slowly, crystals of the solute will appear. Filter the solution to get the crystals and dry the crystals using tissue paper.
