    Discussion | 12 | 7) Conclusion | 13-14 | 8) References | 15 | ABSTRACT This experiment is about steam distillation by using Dalton’s Law. The objectives of this experiment are to demonstrate a separation of a mixture by using steam distillation and next to prove that Dalton’ Law and ideal gas law are applicable in steam distillation. Dalton’s Law; While Ideal Gas Law; This experiment is conducted by placing 2mL of Turpentine and 15mL of water into the flask.10mL graduated

    Fractional distillation was used in this experiment. This is one of two ways for distillation‚ the other being simple distillation. However‚ with a simple distillation‚ the difference of boiling points between the substances must be more than 40 to 50 degrees C. A fractional distillation column is needed in a fractional distillation. The column in a fractional distillation column provides a temperature gradient where the temperature is lower at the top of the column and the temperature is greater

    Chromatography: How can we separate a mixture? Purpose The chromatography lab is to understand how molecules with similar molecular properties can be separated with paper chromatography. These differences will be interpreted to see the distinction of separate chemical substances. Pre Lab Questions 1. Explain capillary action as it pertains to water and paper. Capillary action makes water draw up the paper. As paper absorbs water mixes with the solutions in the paper. 2. What is the

    Paper chromatography is an important separation technique that depends upon differences in how strongly the dyes are adsorbed onto the paper (stationary phase) and how soluble the dyes are in the developing solvent (mobile phase). In paper chromatography‚ a small amount of the mixture to be separated is placed close to the edge of a piece of paper. The edge of the paper is then immersed in a developing solution. As the developing solution ascends up the paper by capillary action‚ the. components

    eugenol in the basic aqueous layer‚ and acetyleugenol in the organic layer. The basic aqueous layer can be acidified to re-extract eugenol from it. And the organic layer can be dried and concentrated to yield acetyleugenol The principle of steam distillation is based on the fact that two immiscible liquids will boil at a lower temperature than the boiling points of either pure component‚ because the total vapor pressure of the heterogeneous mixture is simply the sum of the vapor pressures of the individual

    using it. It is done by a method called fractional distillation which involves separation of two or more liquids having different boiling points. The refining is done by changing the liquid into its gaseous state and then cooling the gaseous mixture at controlled temperatures such that at a time only one of the vapours having boiling point I liquefies first. This is generally done by a special tower called fractionating column. Fractional distillation of petroleum Crude petroleum is heated to a temperature

This lab will help guide you in the direction to predict the regioselectivity and activation vs. deactivating powers of the nitro-group. Gas Chromatography will be used to analyze compounds that can be vaporized without being decomposed. GC is also used to check the purity of a substance‚ and separating the
