desiccant and absorbs the moisture. Other chemicals, such as cobalt chloride, are used as humidity indicators, changing colors according to hydration. For instance, the copper sulfate used earlier in the semester was stated to be CuSO 4, but it actually had absorbed 5 moles of water for every 1 mole of CuSO 4 and should have been

chemlab.truman.eduGas Chromatography: Principles and Determination of Percent Alcohol INTRODUCTION In this experiment you will apply gas chromatography to the separation of a water-ethanol mixture. This method is often used in the determination of alcohol (i.e. ethanol) in blood or urine.
Titration of the Weak Acid Potassium Hydrogen Phthalate …
chemlab.truman.edu(acid) (base) In this experiment you will determine the amount of acid present by titration with the strong base NaOH. Since it is hard to prepare a NaOH solution of accurately known concentration directly from the solid, you will need to standardize your NaOH solution against a precisely weighed amount of standard acid.
Determination of Mg by Titration with EDTA
chemlab.truman.eduThe endpoint of the titration is determined by the addition of Eriochrome Black T, which forms a colored chelate with Mg2+ and undergoes a color change when the Mg2+ is released to form a chelate with EDTA. While it is possible to achieve relatively good results by titration with
The Gravimetric Determination of Nickel
chemlab.truman.eduThe Gravimetric Determination of Nickel INTRODUCTION Nickel(II) forms a precipitate with the organic compound dimethylglyoxime, C4H6(NOH)2. The formation of the red chelate occurs quantitatively in a solution in which the pH is buffered in the range of 5 to 9. The chelation reaction that occurs is illustrated below.
