The difference of potential between two solutions of a substance at different concentrations can be calculated from the equations used to give the diffusion constants.
caffeine concentrations to which consumers could be exposed.
In ordinary cases possible changes in the concentrations only affect the electromotive force by a few parts in a hundred, but, by means such as those indicated above, it is possible to produce such immense differences in the concentrations that the electromotive force of the cell is not only changed appreciably but even reversed in direction.
If the temperature at which this dense spontaneous shower of crystals is found be determined for different concentrations of solution, we can plot a "supersolubility curve," which is found generally to run roughly parallel to the "solubility curve" of steady equilibrium between liquid and already existing solid.
High concentrations of carbon dioxide in the blood, causes the blood to become more acidic.
