3. In streaming potential measurements, an electric field is created between two measuring electrodes when a liquid (an electrolyte) is forced to flow past a stationary charged surface by applying a hydraulic pressure difference, p. The potential between the electrodes is referred to as the streaming potential, Estr, which can be calculated by an equation similar to the one given for electro-osmosis. However, the electrokinetic ratio V/I of the electro-osmosis equation needs to be replaced by the ratio (Estr / p). If an electrolyte such as 10-3M NaCl having a conductivity 1.26x10-2ohm-1m-1 at 25ºC is forced to flow in a glass capillary tube with an applied pressure of 760 mm Hg, what would be the streaming potential measured between the electrodes? Zeta potential at the glass-electrolyte interface is to be taken 50mV.
