activity
"The activity of a dissolved species in solution is the ""effective"" concentration of that species. In an ""ideal"" solution, the molecules in the solution do not interact with each other and the concentration and the activity are identical. This is the case for very dilute solutions. In a ""real"" solution, there is a certain interaction between the molecules resulting in a diminished ""activity"" of the molecules toward the outside world, and the solution behaves like it would contain lower concentration of the dissolved species than it actually does. The activity can be expressed as the product of an ""activity coefficient"" and the concentration. "

Activity
In adsorption chromatography, the relative strength of the surface of the packing. For silica gel, the more exposed the silanol groups, the more active the surface. Activity can be controlled by adding water or another polar modifier, which is hydrogen bonded to the active sites, thereby reducing the surface activity.
