The Potentiometric Estimation of Chloride in Water Extracts of Soils1
- B. G. Davey and
- Marion Joy Bembrick2
The thermodynamic equation for the e.m.f. developed between Ag-AgCl electrodes in a cell with liquid junction is derived for a complex electrolyte system containing Cl. The equation is tested experimentally and a method devised to determine Cl in water extracts of soil. The range of the method, 5 × 10-5M to 10-2M Cl, is much more sensitive than either the electrometric, conductometric or the Volhard methods currently used in soil analysis.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
