WHAT IS ABSORBTION?
In chemistry, absorption is a physical or chemical phenomenon or a process in which atoms, molecules, or ions enter some bulk phase – gas, liquid, or solid material.Physical absorption is made between a gas mixture or part of it and a liquid solvent. It involves the transfer of mass that takes place at the interface between the liquid and the gas and the rate at which the gas diffuses into a liquid. This type of absorption depends on the solubility of gases, the pressure and the temperature.Chemical absorption or reactive absorption is a chemical reaction between the absorbed and the absorbing substances. Sometimes it combines with physical absorption. This type of absorption depends upon the stoichiometry of the reaction and the concentration of its reactants.
