Aliquot Method
SOLVED: A) Chloride in a brine solution is determined by the Volhard method. An aliquot of 10.00 mL is treated with 15.00 mL of 0.1182 M AgNO3 solution. The excess silver is titrated with a standard 0.101 M KSCN solution, consuming 2.38 mL to reach the red Fe(SCN)2 endpoint. Calculate the chloride concentration in the brine solution in g/L.B) A hydroxide solution is standardized by titrating 0.8592 g of primary standard potassium hydrogen phthalate to a phenolphthalein endpoint, consuming 32.67
