ABSTRACT Determining the melting point of a solid organic compound is the easiest way to identify the compound and determine its purity at the same time. For actual samples of compounds‚ the melting will occur over a range of temperatures making the melting points into a melting “range”. The difference between the temperature at which the sample begins to melt and the temperature at which it finishes melting‚ or the magnitude of the melting range‚ is a very important criteria of determining the

#1: THE PURITY AND PURIFICATION OF SOLIDS MELTING POINTS ABSTRACT Melting points of different mixtures of naphthalene and biphenyl were examined in this lab. Samples of these various mixtures were collected and tested by different individuals in the lab in order to find the eutectic point of biphenyl. Unknown substances were then tested using the mixture melting point method in order to determine their identities. INTRODUCTION The melting point of a solid is the temperature where the

Although this nation has long been called a “melting pot”‚ one would not have to look too deep into that analogy to see that it may not be the best way to describe the combination of people from various parts of the world that have chosen to live here in the United States.
