Evaluate the content of chloride in the sample in mg cl-/ml

Reference no: EM13649565

The volumetric determination of chloride in biological fluids is carried out with standard Hg2+ solution in the presence of diphenylcarbazide as indicator, whereupon the following reaction takes place:

2Cl- + Hg2+ <--> HgCl2

A 10.00 mL portion of a urine sample is titrated with 15.04 mL Hg(NO3)2 solution. In the standardization of the Hg(NO3)2 solution, 35.67 mL were consumed to titrate a solution containing 0.2045 g of NaCl (58.44 g/mol). Calculate the content of chloride (35.45 g/mol) in the sample in mg Cl-/mL.
