July 14‚ 2009 Experiment 6: Fractional Distillation. Separation of Petroleum Hydrocarbons Abstract: A mixture of cyclohexane and toluene were separate from one another by fractional distillation in order to measure the composition of each fraction and prepare the sample for gas chromatography. Introduction: Distillation has been used since antiquity to separate the components of mixtures. This method has been used to manufacture different organic chemicals but the most recent application

Experiment #4A- A Separation and purification Scheme Amena Alkeswani‚ PHCC Dhanlal Murally‚ PHCC September 27‚ 2012 Abstract: There are millions of different organic compounds. Most of them are found in mixtures and in order to achieve a pure form they need to be separated‚ isolated‚ and purified. However‚ there are endless numbers of possible mixtures‚ which make it impossible to have a pre-designed procedure for every mixture. So chemists often have to make their own procedures. The purpose

| Experiment 2 | Calorimetry | | Chemistry 1310 | 7/21/2013 | | This experiment is to calibrate a constant pressure calorimeter to experimentally determine a series of heats of reaction that will be used to predict the enthalpy of reaction for another reaction using Hess’ Law and to determine heats of dissolution for a number of ionic salts that will be used to predict lattice energy again by using Hess’ Law. Heat may increase during experiment and undergo exothermic reaction

An ideal gas has the following equation of state (an equation which relates various thermodynamic properties for a substance‚ such as pressure‚ temperature and molar volume): Pv = RT P - pressure v - molar volume R - universal gas constant T - absolute temperature Clearly the molar volume depends on temperature and pressure‚ so if two gases are at different conditions then they
