Abstract: The Molecular Weight of a Volatile Liquid The purpose of this experiment was to-through the application of the Ideal Gas Law (PV = nRT)-determine the molecular weight of an unknown, volatile liquid (unknown #14). The results of this lab yie
Experiment #8: The Entropy and Enthalpy of the Dissolution of Borax Abstract In this experiment, the change in enthalpy and entropy of tetraborate and sodium ions from borax was investigated. It was concluded that the change in enthalpy for the disso
Abstract: Heats of reaction and Hess' Law In a calorimetric experiment such as this, both the liberation and consumption of heat is measured and analyzed by the rise and fall of temperature of the system (defined as the reactants in the calorimeter).
Abstract: Weak Acid and Buffer Systems The purpose of this experiment was to titrate three acids (formic, acetic, and propionic) to calculate the equivalence point, Ka, and pKa values for each. For formic acid, the amount of NaOH needed to reach the
1 Extraction and Analysis of Lavender Oil Abstract In this experiment, the presence of four primary molecular components of lavender oil were identified using gas chromatography. From the analysis of the gas chromatographs, the chemical composition o
