Synthesis of Isopentyl Acetate (Banana Oil) Using A Fischer Esterification Reaction Purpose: The purpose of this experiment is to synthesize Isopentyl Acetate using a Fischer esterification reaction. Fischer esterification is an acid-catalyzed condensation of an alcohol and a carboxylic acid‚ yielding an ester and water. Isopentyl Acetate has the scent of banana oil‚ once synthesized it will be purified by distillation. Then the analysis of the sample using H NMR and IR will determine purity

An Experiment to find the Concentration of a Sample of Acid Rain Plan Aim When a metal is extracted from its ore often sulphur dioxide is produced. When sulphur dioxide is dissolved in water it forms a strong acid called sulphuric acid. Sulphuric acid is often sold as a useful by-product‚ but also gets into the water cycle and forms acid rain. In this experiment‚ I have been given a sample acid rain of concentration between 0.05 mol dm-3 and 0.15 mol dm-3 and my aim is to find out exactly what

Flame Test Lab Morgan Chemistry CP 5/30/14 Abstract- In the flame test lab‚ the flame test was performed to excite the electrons in the samples and observe the color of the flame. The flame emits a color because each element has an exactly defined emission spectrum‚ which one can use to identify them. For example‚ NaCl was highlighter yellow‚ Sr(NO3)2 was sun orange‚ CuCl2 was turquoise‚ LiCl was neon red‚ KCl was solar flare yellow‚ and BaCl2 was Voldemort green. Introduction- In Bohr’s

Abstract: The main reason for this experiment is to prepare a simple soap made from vegetable oil. The physical properties will be tested in order to demonstrate the reactions that occur. The experiment can conclude that the vegetable oil had a primary fatty acid called linoleic acid‚ which was evident during the saponification reaction. The simple soap did appear to be a good emulsifier because the soap did dissolve in the mixture of mineral oil and water. In hard water the calcium and magnesium
