How could you be certain a peak in the soda was caffeine and not another substance with similar retention time
A sample of the unknown complex is analyzed and has an absorbance of 0.528. What is the molar concentration of Cu^2+ ions in the unknown solution?
Recall from class that we estimated the pi bond in ethylene to be about 350 kJ/mol. Use the same approach to estimate the strenghth
which caused the CO2 in the sample to precipitate as BaCO3. The excess base was back-titrated to a phenolphthalein end point with 23.6ml of .0108 M HCl. What is the concentration of CO2 in the air in parts per million? use 1.98g/L for the density ..
