Distinguish between the meaning of the terms adsorption and absorption. Given one example of each. |
|
Answer» This phenomenon of attracting and retaining the molecules of a substance by a solid (or a liquid) on its surface resulting into a higher concentration of the molecules on the surface is known as adsorption. Absorption is different from adsorption. In absorption, the substance is uniformly distributed throughout the body of a solid or a liquid. `NH_(3)` gets adsorbed on the charcoal where as `NH_(3)` when comes in contact with `H_(2)O` gets absorbed by forming `NH_(4)OH` solution of uniform concentration. |
