The objective of this lab was to identify an unknown compound by determining the melting point range using fast and slow ramps. Also‚ to determine the eutectic point of Urea and Cinnamic Acid. An unknown compound that was numbered 8 was chosen. A small amount of the unknown compound was placed in a weighing paper using a spatula. The weighing paper was folded in half twice and then was grinded using a spatula. After the unknown compound was grinded about 1-2mm was added into a capillary tube. A

Melting Points Elizabeth McGrail Organic Chemistry I 25 January 2013 ABSTRACT The objectives of this lab are‚ as follows; to understand what occurs at the molecular level when a substance melts; to understand the primary purpose of melting point data; to demonstrate the technique for obtaining the melting point of an organic substance; and to explain the effect of impurities on the melting point of a substance. Through the experimentation of three substances‚ tetracosane‚ 1-tetradecanol and

We were tasked with finding the molar mass of an unknown compound using the colligative property of Freezing Point Depression. The way we did this was first finding the temperature at which ice crystals form for just regular BHT. Luckily thanks to our TA we were given temperature probes so we could pinpoint exact

Color impurities present in the solid acetaminophen will be removed and then the decolorized product will be collected on a Büchner funnel for further purification by crystallization. Purity will then be determined by melting point. Introduction: Acetaminophen is commonly used as an analgesic to reduce pain and fever. In this experiment it is prepared by the reaction of p-aminophenol with acetic anhydride‚ as illustrated below. Results: Isolation of crude acetaminophen The color
