  2. Freezing-point depression - Wikipedia

    en.wikipedia.org/wiki/Freezing-point_depression

    Freezing-point depression is a drop in the maximum temperature at which a substance freezes, caused when a smaller amount of another, non-volatile substance is added. Examples include adding salt into water (used in ice cream makers and for de-icing roads), alcohol in water, ethylene or propylene glycol in water (used in antifreeze in cars ...

  5. Extractive distillation - Wikipedia

    en.wikipedia.org/wiki/Extractive_distillation

    Extractive distillation is defined as distillation in the presence of a miscible, high-boiling, relatively non-volatile component, the solvent, that forms no azeotrope with the other components in the mixture. The method is used for mixtures having a low value of relative volatility, nearing unity. Such mixtures cannot be separated by simple ...

  6. Volatility (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Volatility_(chemistry)

    Volatility can also describe the tendency of a vapor to condense into a liquid or solid; less volatile substances will more readily condense from a vapor than highly volatile ones. [1] Differences in volatility can be observed by comparing how fast substances within a group evaporate (or sublimate in the case of solids) when exposed to the ...

    For example, the strong electrolyte MgCl 2 dissociates into one Mg 2+ ion and two Cl − ions, so that if ionization is complete, i = 3 and =, where is calculated with moles of solute i times initial moles and moles of solvent same as initial moles of solvent before dissociation.

  8. List of purification methods in chemistry - Wikipedia

    en.wikipedia.org/wiki/List_of_purification...

    Evaporation removes volatile liquids from non-volatile solutes, which cannot be done through filtration due to the small size of the substances. Liquid–liquid extraction removes an impurity or recovers a desired product by dissolving the crude material in a solvent in which other components of the feed material are soluble.

  9. Solid-phase microextraction - Wikipedia

    en.wikipedia.org/wiki/Solid-phase_microextraction

    Solid-phase microextraction sampling. Solid phase microextraction, or SPME, is a solid phase extraction sampling technique that involves the use of a fiber coated with an extracting phase, that can be a liquid or a solid (), [1] which extracts different kinds of analytes (including both volatile and non-volatile) from different kinds of media, that can be in liquid or gas phase.
