WebbHis equation is widely used in cell physiology and neurobiology. The carbon electric filament lamp then in use was dim and expensive because it required a vacuum in its bulb. Nernst invented a solid-body radiator with a filament of rare-earth oxides, known as the Nernst glower , it is still important in the field of infrared spectroscopy . WebbCalculate Equilibrium Potential with Nernst Equation The gradients acting on the ion will always drive the ion towards equilibrium. The equilibrium potential of an ion is calculated using the Nernst equation: The Nernst Equation Eion = 61 z log [ion]outside [ion]inside E i o n = 61 z l o g [ i o n] o u t s i d e [ i o n] i n s i d e
WebbNernst Equation. The Nernst equation is an important relation which is used to determine reaction equilibrium constants and concentration potentials as well as to calculate the minimum energy required in electrodialysis as will be shown later.
