Purpose: a) Determine the melting points of two organic compounds known to have the same melting range when pure. b) Determine the mixture melting point of a mixture of the two pure compounds. c) Identify an unknown organic compound by determining its melting point and mixture melting point. Procedure and Observations: Using the procedure outlined in Appendix A of the Lab Manual‚ approximately equal samples of p-Nitrophenol and acetanilide‚ which are known to have the same melting range

a series of prefixes and suffixes to name a certain compound. This system is also highly favored because its way of naming compounds is not only easier to understand and unambiguous‚ but it is also usually shorter than the common way. The IUPAC system’s uses include naming binary compounds between a metal and nonmetal‚ naming binary compounds between two nonmetals‚ naming polyatomic ions‚ and naming acids and bases. To name binary compounds between a metal and a nonmetal‚ there are two different

chemical research. He was raised as Roman Catholic. He went to Switzerland to study chemistry at the Swiss Federal Institute in Zurich where he earned his PHD degree in 1890. His thesis dealt with the spatial arrangement of atoms in nitrogen compounds. He then continued his study for a year in Paris before returning to Swiss Federal Institute (1892) to teach organic chemistry. Then the following year he became associate professor at the University of Zurich and director of its chemical laboratory

Chromatography is the separation of compounds to allow us to see the different colours of that compound‚ for instance we may use chromatography in a school lab to see the real colour compounds of plants and grass‚ by using chemicals such as acetone we it will allow the object to break compounds and thus we can see the true colour of the grass. In today’s society there are many real world applications which use the chromatography technique in their line of work‚ an example of one of these applications

phase is silica gel (SiO2) which is very polar compound‚ while the mobile phase is 0.5% acetic acid which has less polar. Also‚ as we know‚ the compound will rather to stay with stationary phase or travel with mobile phase depend on its polarity. The result show as that the polarity of the solvent is the key factor for the compound to travel with it or stay in stationary phase. The result show us that the Caffeine has more polarity than other compounds because it stays in stationary phase which has

For instance certain compounds can be listed on the nutrition label and we can’t even taste or see them.
