Re: can you desalinate water in a centrifuge? - MadSci

The reason for this inefficient "desalination" is the tendency of the dissolved salt ions to redistribute themselves in the space where their concentration is reduced. This entropy-driven tendency is pitched against the centrifugal force. Entropy thus plays a much more important role if we are dealing with a true solution (like that of sodium ...
