Mixture Melting Points Abstraction Determining the melting point is very significant in order to identify an unknown. In this experiment‚ measuring the melting point was done by using melting point apparatus. The melting point of the unknown sample #10 was 111.5˚C. There were two possible compounds which were dibenzoyl ethylene and o-Toluic acid because their melting points were 111.2˚C and 109.8˚C when each compound was mixed with the unknown. Therefore‚ the unknown #10 was dibenzoyl ethylene

Introduction The melting point is defined as the temperature at which the solid is in equilibrium with its liquid‚ and this characteristic is very unique‚ so a substance can be determined by the melting point. Determination of the melting point is very important technique in many areas of chemistry especially‚ in organic chemistry area because the melting point is really significant in order to identify the purity and the identity of a substance. Measuring the melting point is a fast and cost-effective

Lab/ Chem 234 02/17/13 Lab 2: Melting Points Purpose: To determine the purity of a substance using melting point as physical property. We must also learn how to identify an unknown compound using its melting point. We got to identify an unknown compound using mixture melting point and finally we must learn to obtain an accurate melting point using Mel-Temp apparatus. Procedure: Set voltage to obtain the desired heating rate at the anticipated melting point range. The voltage control controls

Melting Point Determination Lab Materials: Graduated pipette Capillary tube Tin wipe Sample Melting temperature apparatus Thermometer Procedure: Take open end of capillary tube and tap it gently into sample. Take tin wipe and place over the opening. Gently tab it so the sample will funnel to the bottom of the tube. You may also use a graduated pipette to accomplish this. Now‚ place the capillary tube in the designated spot in the melting apparatus‚ and once placed‚ turn the apparatus
