A new and easy concept for introducing the chemical potential μ even at introductory high school level is presented as well as the application of this quantity on the description of colligative phenomena such as osmosis. Find out among other things how to construct your own “osmometer” by use of a carrot.

Because we are interested in a first basic knowledge of the chemical potential, we consider the values at the moment as given.. Each realisable reaction is comparable to a kind
While amount of substance goes from high to low chemical poten- tial, electric charge is lifted from low to high elec- tric
For example, it is possible to predict by means of the chemical potential whether a considered reaction is possible or not, which yield can be expected, what can be done to
The chemical potential, defined as a partial derivative of a quantity which contains both energy and entropy, seems to be complex beyond despair.. As indicated by its name, the
The concept can be expanded easily to colligative phenomena (such as osmosis), diffusion processes, surface phenomena (such as adsorption), and so on.. Furthermore, the same
