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

Which of the 2 unknown substances was which? How did you figure this out? The two unknown substances were the methanol and propenol because each of them were being tested in this experiment to discover the boiling point of each of these alcohols by analysing each of their temperatures to eventually

Melting Point and Boiling Point of Organic Compounds Bongo‚ Sayre‚ J1 1Student‚ Organic Chemistry 1 Laboratory / B11‚ School of Chemical Engineering‚ Chemistry and Biotechnology‚ Mapúa Institute of Technology ABSTRACT The melting point of a substance is the temperature at which the material changes from a solid to a liquid state while the boiling point is the temperature at which it changes from liquid to solid. In this experiment‚ the main objectives were to determine the effects of the following

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

Lab Title: "The Effect of Salt on the Boiling Point of Water" Lab Question: How does adding salt to water affects it’s boiling point? Prediction : In this paper‚ a newly proposed model based on solvation between pure solvent and salt for prediction of salt effect on vapor–liquid equilibria is presented by using only the vapor pressure depression data of pure solvent+salt systems that compose the mixed solvent with salt system Materials : 200 mL of distilled water‚ 2 beakers

Based on my temperature value and my lab measurements‚ I calculated that the water density would be 2.16 (g/mL). This calculation of density does not match up with the density in the table provided. The table calculations would give the water with 22ºc a density of 0.99770. My calculation or lab measurements must be wrong because

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

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
