Cross-phenomenological coefficients. Part 4.—Electro-osmosis of acetone

Abstract

Electro-osmotic velocity, electro-osmotic pressure and rate of permeation for acetone/Pyrex sinters are reported in this paper. The range of validity of linear phenomenological relations has been experimentally ascertained. L₁₂ is found to be constant up to potential differences of about 440 V. The second-order coefficient L₁₁₂ has been estimated from measurements of electro-osmotic pressure and the rate of permeation in the presence of pressure and potential gradients. Streaming potential measurements are also recorded and L₂₁ has been found to be constant up to pressure differences of 100 cm of acetone. Onsager's reciprocal relation has been verified.
