------------------------------------------------- MELTING POINT AND BOILING POINT OF ORGANIC COMPOUNDS ------------------------------------------------- ABSTRACT The melting point (MP) and the boiling point (BP) are probably the most widely used physical constant in the field of science. Determining the boiling point and the melting point of a compound helps you to characterize an unknown solid in a quick‚ easy and cheap way. The temperature at which a compound turns from a solid state to a liquid state is known to be the

Compounds that have different solubility at different temperature usually can be recrystallized. Formulas and Structures: Benzoic Acid Methanol Percent Recovery: Indicates how much of the

test can measure the case to core depth parts. Micro-hardness testing is required where the superficial hardness test is not conceivable due to material’s small geometrical shape. The welded part we were going to examine‚ experienced the similar criteria since the welded bead of the joint was way too small. To test the hardness of our welded area we had gone through a micro-hardness test using a Shimadzu micro-vicker hardness testing machine. In the following practise‚ we used a micro-vicker tester

2. Microfluidics-device testing In this step‚ we use 10 µm polystyrene beads as a cell for testing the trapping ability of the device. The polystyrene beads were mixed with deionized water (DI water) and surfactant (Tween 20) in the ratio of 100: 1: 10 v/v/v. The fast green FCF (C37H34N2O10S3Na2) was added to the mixing solution for increased the particle visualization and then the solution was containing into a 10 ml syringe that connected to the device at an inlet.

Organic Chemistry I Simple and Fractional Distillation The Simple and Fractional distillation experiment was divided into two parts. We split up the procedure in this experiment. My group did the simple distillation and we received the Fractional distillation from another group in class. In this experiment‚ we examined the effectiveness of fractional and simple distillation to determine which is more successful at extracting a pure sample. This experiment was very successful. We are able to

Water Testing Lab Conclusion In this lab‚ chemical tests were used to check for the presence of calcium‚ chloride‚ and sulfate ions in water samples. To do this‚ the testers started with five samples: a reference‚ a sample of only the chemical being tested for‚ a control‚ distilled water‚ two home water samples‚ and a school water sample. To test for the ions in the water‚ a chemical that would react with the ion and create a precipitate was added. If the precipitate was not easily visible‚ a

Post-Lab Report for Experiment 2: Cooperative Identification of an organic Solid October 6‚ 2013 Introduction: This experiment was focused on the cooperative identification of organic compound by its chemical properties such as: slow melting point‚ mixed melting point‚ Rf values in TLC experiment‚ IR spectrum analysis‚ and H NMR spectra. Such data can provide the the identity of functional groups and the identity of the compound itself. In this experiment
