EXPERIMENT 3 FAJANS DETERMINATION OF CHLORIDE
alpha.chem.umb.edudetermination of chloride ions. The Analytical Reaction The reaction of AgNO3 with Cl-may be represented as: Ag+ + Cl-= AgCl (s) Suppose that we have a sample containing an unknown quantity of chloride ions. The number of moles (or weight) of chloride might be determined by titration with a silver nitrate solution of known concentration, C.
Determination of Chloride Ion Concentration by Gravimetry
www.canterbury.ac.nzThis method determines the chloride ion concentration of a solution by gravimetric analysis. A precipitate of silver chloride is formed by adding a solution of silver nitrate to the aqueous solution of chloride ions. The precipitate is collected by careful …

Precipitation Titration: Determination of Chloride by the ...
academic.brooklyn.cuny.eduIn this experiment, the amount of chloride in an unknown sample was determined by Mohr titration. The titration was carried out at a pH between 7 and 10 because chromate ion is the conjugate base of the weak chromic acid (2, 3). Therefore, when the pH is lower than 7, chromate ion is protonated and the chromic acid form predominates in the ...
