Lyotropic
Ions arranged in series.
Can be used in context with salts, radicals in which they are arranged decending order in magnitude to the effect of a given solvent.

Antipolyelectrolyte
Increasing chian expansion when increasing the ionic strength

Ionic Strength
Relates to how ions effect a solution. Where activity is NOT equal to concentration.
Activtiy = concentration (mol/L)  x activity coefficent
