A 1.1237 -g alloy sample was analyzed for its copper content iodometrically. The alloy was dissolved in hot, concentrated nitric acid and prepared for analysis. The addition of excess KI(aq) solution precipitated the copper as cuprous iodide and liberated elemental iodine according to the following reaction:
Cu2+(aq) + I-(aq) ? CuI(s) + I2(aq)
The liberated iodine was titrated against a standard thiosulfate solution until the disappearance of the blue starch-iodine indicator complex according to
I2(aq) + 2S2O32-(aq) ? 2I-(aq) + S4O62-(aq)
Calculate the percent copper in the sample if 28.46 mL of a 0.4904 M thiosulfate solution was required to react with the liberated iodine.
We find coesite and stishovite in shocked Coconino Sandstone at meteor Crater. We infer that coesite and stishovite formed from the transformation of quartz at high pressure and temperature.
