donnian Sentence Examples
- The donnian equilibrium, named after the Scottish chemist Frederick Donnan, occurs when a semipermeable membrane separates two solutions containing ions of different concentrations.
- The Donnan effect results in an unequal distribution of ions across the membrane, where more ions of the species present in lower concentration are found on one side of the membrane than on the other.
- Donnan equilibria are essential in understanding a variety of biological and chemical phenomena, such as the distribution of ions across cell membranes and the behavior of polyelectrolytes.
- Donnan equilibria can be used to separate ions based on their size and charge, a process known as Donnan dialysis.
- The Donnan effect is also utilized in the development of ion-exchange membranes, which are used in fuel cells, batteries, and water purification systems.
- In a Donnan equilibrium, the concentration of the salt inside the membrane is higher than the concentration outside the membrane, due to the presence of the charged groups.
- The Donnan potential, which is the difference in electrical potential between the two sides of the membrane, arises from the unequal distribution of ions across the membrane.
- The magnitude of the Donnan potential depends on the concentration gradient of the ions, the charge of the ions, and the temperature.
- Donnan phenomena are also observed in systems where there is a difference in the chemical potential of ions across a membrane, such as in the case of electrochemical cells.
- Understanding Donnan equilibria is crucial for developing new materials and technologies in fields such as electrochemistry, biophysics, and membrane science.
