Sodium acetate is used to coat DNA before subjecting it to this process using (*) cold ethanol.
Systems without convection undergoing this process can show Liesegang rings. Ammonium sulfate is used to do this to proteins, and the Hofmeister series arranges salts by their ability to do this to proteins. Whether this process is reversed by the addition of KOH is useful for distinguishing primary or secondary amines in the Hinsberg test. Sodium acetate is used to coat DNA before subjecting it to this process using (*) cold ethanol. The supernatant is what's left over after this process. This process can be triggered by adding an impurity to a supersaturated solution or adding a common ion, and occurs when the Ksp is really small. For 10 points, name this process in which a solid falls out of solution.
Systems without convection undergoing this process can show Liesegang rings.
