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

His contributions to society helped many people at this time‚ and they went on for generations. As stated by Donovan 455‚ in 1748‚ when studying electricity and conducting experiments‚ he developed his Theory of Points which states that blunt metal objects don’t attract as much electricity as pointed objects. Other than that there were so many more inventions

BOILING POINTS AND MELTING POINTS PART 2 Name: Grethel Zegarra Date of Lab: October 26‚ 2010 Date lab is due: November 2‚ 2010 HYPOTHESIS The boiling point in degrees Celsius will increase as the number of carbon atoms increase. The melting point of the unknown will indicate its mixed substances. The boiling point will increase as a result of the different branching of the OH‚ the melting point will be affected by the different positioning of the OH on the benzene ring. PURPOSE To introduce

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
