Study of natural processes that change concentrations
Solute
These processes can be categorized into two broad groups:
transport
transformation
Transport refers to those processes which move substances through the hydrosphere by physical means. The two primary modes of transport are advection (transport associated with the flow of a fluid) and diffusion (transport associated with random motions within a fluid).
The second process, transformation, refers to those processes that change a substance of interest into another substance
Molecolar Diffusion
Diffusion has two primary properties: it is random in nature, and transport is from regions of high concentration to low concentration, with an equilibrium state of uniform concentration. Think to a bottle of perfume when it is opened in an empty room…..
