    Purpose The purpose of this lab is to find the boiling point of the liquid and find the melting point of the solid. Procedure Boiling point: To find the boiling point of Isopropyl Alcohol I put about 1 mL of it in the test tube. Then I attached the thermometer to the test tube with a rubber band(make sure the thermometer bulb is lined up with the end of the test tube). After that I made a water bath with a beaker and put in the test tube with the thermometer. I then used a burner and a burner stand

    Spectroscopy‚ Boiling point and Melting point. Introduction: - Infrared spectroscopy has also made a break though in medicine. It used to evaluate the kidney stone diseases thus broadening the use of IR in different ways. The purpose of this lab experiment is to identify the unknown solutions using the Infrared Spectroscopy (IR)‚ boiling point‚ and melting point (1). The IR helps to determine the compounds such as a functional group. In order to analyze the compound‚ IR and melting point work the best

    BOILING POINTS AND MELTING POINTS PART 2 Name: Grethel Zegarra Date of Lab: October 26‚ 2010 Date lab is due: November 2‚ 2010 HYPOTHESIS The boiling point in degrees Celsius will increase as the number of carbon atoms increase. The melting point of the unknown will indicate its mixed substances. The boiling point will increase as a result of the different branching of the OH‚ the melting point will be affected by the different positioning of the OH on the benzene ring. PURPOSE To introduce

    DETERMINATION OF BOILING POINTS Introduction: The boiling point of a compound is the temperature at which it changes from a liquid to a gas. This is a physical property often used to identify substances or to check the purity of the compound. It is difficult‚ though‚ to find a boiling point. Usually‚ chemists can only obtain a boiling range of a 2 - 3oC accuracy. This is usually sufficient for most uses of the boiling point. Purpose: The purpose of this experiment is to determine the boiling points

    expected‚ I found that it boiling point was 60C but in my experiment it was 30 C it’s the double of what it should be. Most of the sample like methanol and ethanol was pretty clos to the result that I found on internet. The trial that I did was Butanol again with the hot plates and it took of course much longer to boil and it started to boil before 105 °C like at 103 °C and I didn’t expect that happen maybe because of the boiling water it accelerated the boiling point. I don’t consider my
