Chemical Absorption - an overview ScienceDirect Topics

WebAbsorption occurs when a liquid, such as water, is taken up (or absorbed by) a solid. When this happens, the solid often grows in size or swells. Many examples of absorption are found in cooking. For example, preparing pasta or rice requires absorption of water. WebJun 5, 2024 · A = εℓc A is the absorbance ε is the absorptivity or molar attenuation coefficient in M -1 cm -1 (formerly called the extinction coefficient) ℓ is the optical path length in cm c is the concentration of the chemical species in mol/L or M From this law, note: Absorbance is directly proportional to path length.
