Is there any difference in the practical use between measuring the conductivity of electrical and ionic conduction?
It involves the measurement of mobile ions H +, Na +, Li +, etc.
The following should apply:
Conductivity = (length * current) / (cross-sectional area * voltage)
Should this be done by a "simple" current/voltage characteristic?
Thank you Dr. Snyder for the very helpful answer. So if i measure no aqueous solution, but a solid material where the ions are mobile, i could adjust the size of my sample to "one-dimensional" and take the I-U graph?
Otherwise the impedance measurement should be always suitable for a 2-dimensional sample.(?)
Conductivity in aqueous solutions due to the motion of the ions and the ever increasing temperature is opposite to the conductivity of metals, but closer to that of graphite. It is caused by the nature of the ions and the viscosity of water. At low ion concentration (ultrapure water) to determine the water ionization of conducting ions. All of these processes and hence the conductivity significantly temperature dependent.
what is good method for measurement of ionic conductivity or nyquist plot. please discuss ...... i.e LCR or AUTOLAB
how to measure conductivity of solid & gel electrolyte of lithium polymer battery?
