(5 marks) A solution containing chloride ion was analyzed by the mL sample containing chloride ion was treated with 25.00 mL of 0.2500 M silver nitrate. The precipitated AgCl was removed from the solution by filtration, and 1.00 mL of 0.1000 M Fe3 was added to the filtrate in order to titrate excess Ag with SCN. A volume of 10.67 mL of 0.2380 M KSCN was required for solution to turn red colour. What is the concentration of chloride ion...

A mixture consisting of only iron(III) chloride (FeCl3) and aluminum chloride (AlCl3) weighs 1.0397 g. When the mixture is dissolved in water and an excess of silver nitrate is added, all the chloride ions associated with the original mixture are precipitated as insoluble silver chloride (AgCl). The mass of the silver chloride is found to be 3.0178 g. Calculate the mass percentages of iron(III) chloride and aluminum chloride in the original mixture. Mass percent FeCl3 = % Mass percent AlCl3...

A 0.6407 g sample containing chloride and iodide ions gave a silver halide precipitate weighing 0.4430 g. This precipitate was then strongly heated in a stream of Cl2 gas to convert the AgI to AgCl; on completion of this treatment, the precipitate weighed 0.3181 g. Calculate the percentage of chloride and iodide in the sample separately.

Chloride in a water sample can be determined indirectly by
atomic absorption spectrometry by precipitating chloride as AgCl(s)
with a measured amount of AgNO3 that is excess of the chloride
content of the sample. The AgNO3 is added and the sample is
centrifuged. The remaining Ag+ in the solution (supernatant) is
quantified and the chloride is measured by assuming that chloride
was quantitatively precipitated.
