Anion bridges and salting out

Recent developments in neutron scattering allow us to see how the addition of salt to an aqueous amphiphile induces structural changes that may initiate salting out. A relatively simple process is revealed in which anionic salt bridges form between the alcohol molecule polar groups. These ion bridge...

Summary:Recent developments in neutron scattering allow us to see how the addition of salt to an aqueous amphiphile induces structural changes that may initiate salting out. A relatively simple process is revealed in which anionic salt bridges form between the alcohol molecule polar groups. These ion bridges drive an increase in the water exposure of the non-polar surface, leading to their salting out by the hydrophobic effect.
