CHE 317 "Simple Distillation" Interpretation of Results and the Report In addition to learning the technique of performing a distillation‚ you have had the opportunity to observe at first hand the behavior of a reasonably pure compound in the distillation process. You also measured quantities (temperatures) whose magnitudes you did not know beforehand.

Espejo 3rd year‚ BS Chemistry‚ University of the Philippines‚ Diliman Abstract Dissolved organic matter (DOM)‚ the fraction passing through a 0.45 µm membrane filter‚ is considered poorly understood mixture of organic polymers because of its complexity. Although it largely influences a lot of biogeochemical processes in aquatic environments‚ its characterization is not

Name CH 204 DateExperiment 3: Atomic Spectroscopy Introduction The purpose of the atomic spectroscopy lab experiment was to investigate the relationship between visible light‚ which is the visibly observable range of electromagnetic radiation and the change in energy levels of an element. The line spectrum that was seen in the spectroscope was the evidence of excited atoms emitting electrons and radiating a spectrum of light as it moved from a higher energy state back down to a lower energy level

Experiment 1: Simple Distillation and Boiling Points- Separation of Liquids February 24‚ 2014 Analysis In this experiment‚ the distillation of three groups of two miscible liquids was performed. First‚ Ethanol and 2-Propanol were distilled. The boiling points of ethanol and 2-propanol had a difference of 5°C. The percent recovery for both ethanol and 2-propanol were both 0%. The percent recovery of the intermediate was 96%. The percent efficiency calculated of ethanol and 2-propanol was 0% efficient

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

Techniques for Isolation of Pure Cultures Objective : i. To perform the spread plate and the streak plate inoculation procedure for the separation of the cells of a mixed culture so that discrete colonies can be isolated. ii. To prepare a stock culture of an organism using isolates from the mixed cultures prepared on the agar streak-plate and/or the spread plate. Introduction : In order to be able to adequately study and characterize a certain microorganism‚ microbiologists need to separate
