Deliquescent materials are substances (mostly salts)that have strong affinity for moisture and will absorb relatively large amounts of water from the atmosphere if exposed to it, forming liquid solution.

Osmosis is the diffusion of the movement of water from a region of higher concentration to a region of lower concentration through a cell membrane or other semi-permeable membrane until an equilibrium is reached. It is a special case of diffusion (passive transport).

Definition: the process in which a soluble substance picks up water vapor from the air to fom a solution. In order for deliquescence to occur, the vapor pressure of the water in the air must be greater than the vapor pressure of the saturated solution.
