250.0 ml of the mineral water sample was precipitated with potassium sodium tetraphenyl bromate: K+ + B(C6H5)4-  KB(C6H5)(s). The precipitate was filtered, washed and dissolved in an organic solvent. An excess of HgY2- was added to the solution: 4 HgY2- + B(C6H5)4- +4H2O  H3BO3 + 4C6H5Hg+ + 4HY3- + OH-. The liberated EDTA was titrated with 0.05581 M Mg 2+ solution, which consumed 29.64 mL. Calculate the potassium concentration [mg/l] in the sample.
The calcium content of a milk sample was to be determined by EDTA titration. A sample weighing 0.206 g was mixed with an aqueous buffer at pH 11.5.
