Electrolyte resistivity, cross-flow

The difference in the temperature of the electrolyte at entrance and exit of the lEG during cross-flow technique is an important factor. Rise in the temperature of electrolyte tends to decrease its specific resistance but in contrast to that, the insoluble gas and vapor bubbles increases the resistance as shown in Fig. 7.14. However, in EMM the length of the lEG is very small. In such situations temperature rise will increase the conductivity of electrolyte. But these changes would definitely affect the microfluctuation of flow rate and pressure characteristics of the electrolyte in the lEG. There are many advantages of using hot electrolyte too. An increase in the temperature increase the conductivity and in... 

One of the most important qualities that a medium must possess to be useful in electrochemical science is an ability to support current flow. Electrochemical reactions always produce or consume ions at electrodes, and the electrolyte provides the pathway for ions to flow between and among electrodes in the cell to maintain charge balance. The ability of a phase to support current flow by motion of charged particles (ions in an electrolyte) when an electric field exists within the phase is called the conductivity, usually abbreviated as K. Conductivity has units of ohm cm sometimes called siemens cm Conductivity is a property of a phase or material for an electrolyte phase of uniform cross-section of area A and length L, whose electrical resistance is R, the ionic conductivity is given by K = (1IR)(L/A). Conductivity is the inverse of resistivity, usually abbreviated as p, with units of ohm cm. Representative values for ionic conductivity for some commonly used solvent-electrolyte combinations in electrochemistry are presented in Table 3.1.
