Engineering and Chemistry Muralla St.‚ Intramuros‚ Manila Melting Point and Boiling Point of Organic Compounds Group No. 5 Manacup‚ Cris Vincent L. Oblena‚ Adrian D. Ong‚ Joshua Jyro B.* *Leader ABSTRACT In compounds‚ two of the physical properties affected by the varying structures are melting point and boiling point. Through the use of the Thomas-Hoover Melting Point Apparatus or the micro method‚ the melting and boiling point of organic compounds are now determined. The aim of this experiment

Boiling Point Elevation 4-4 Boiling Point Elevation If you dissolve a substance such as ordinary table salt (NaCl) in water‚ the boiling point of the water will increase relative to the boiling point of the pure water. In this assignment‚ you will dissolve a sample of NaCl in water and then measure the boiling point elevation for the solution. 1. Start Virtual ChemLab and select Boiling Point Elevation from the list of assignments. The lab will open in the Calorimetry laboratory with a calorimeter

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

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 melting point. On the

BOILING POINT G1 Decreases going down. Because metal bonds get weaker. Less energy is required this metallic bonding. BOILING POINT G 17‚18 Increases. Because the atomic size incrases. The molecules are attracted by intermolecular forces. Going down the group‚ the intermolecular forces increases. More energy is needed to overcome these stronger forces. DENSITY Because mass increases faster than volume. REACTIVITY OF GROUP 1 The number of occupied shells increases. The atomic size increases

Sample Lab Report for CHM 152 Name Lab Partner(s) Abstract: The physical properties‚ including the boiling point‚ density‚ and refractive index were measured for unknown liquid #16. The infrared (IR) spectrum of the compound was also taken. Based on the data collected‚ it was determined that the compound was likely to be salicylaldehyde. Introduction The purpose of this experiment was to determine the identity of an unknown organic liquid by measuring some of its physical
