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.

academic.brooklyn.cuny.edua simple, direct and accurate method for chloride determination. In 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

hoffman.cm.utexas.eduA protein determination method which involves the binding of Coomassie Brilliant Blue G-250 to protein is described. The binding of the dye to protein causes a shift in the absorption maximum of the dye from 465 to 595 nm, and it is the increase in absorption at 595 nm which is monitored. This assay is
