WebAn automated method is described for the determination of chloride in biological fluids using a mercuric 2,4,6-tri-(2-pyridyl)-1,3,5-triazine reagent. Results obtained by this method compared favourably with those obtained by coulometric titration. The same reagent was used manually to measure the small amounts of chloride in sweat. WebThe volhard method is an indirect or back titration method in which an excess of a standard solution of silver nitrate is added to a chloride containing sample solution. The excess silver is then back titrated using a standardized solution of potassium or ammonium thiocyanate with ferric ion as an indicator.
