# Soluble Ion separation [closed]

Is it possible to separate ions dissolved in solution? I know that the charges have to be balanced, so thinking that maybe it is possible to artificially give that charge? Take for example, sodium hydroxide solution, would there be a way to put all the sodium cations in one area separate from the hydroxide anions?

• Ever heard about Coulomb's law? Electric forces are really, really strong, about as strong as the strongest thing you can imagine, only stronger. Feb 2 at 8:35
• There is a very well established ion separation technique, it is called ion-chromatography. You can "isolate" a given ion of interest from solution. Keep in mind that even in that technique, the charge balance is always maintained. Wikipedia has a nice detailed article. Feb 2 at 14:27
• Applying Coulomb's law, the force necessary to separate $1$ micromole $\ce{Na+}$ from $1$ micromole $\ce{Cl-}$ at a distance of $1$ meter is about $\pu{10^{12}}$ Newton. It is so huge that it cannot be represented by any reasonable way. And it would be even much greater if the separation distance would be smaller. If the separation distance is $1$ micron ($\ce{10^{-6}}$ meter) instead of $1$ meter, Coulomb's law states that this force would be about $\pu{10^{24}}$ Newton. It is not possible to find a reasonable way for describing such a huge force. Feb 4 at 20:13
