NITRATION OF METHYL BENZOATE Purpose: The main objective of this experiment was to synthesize methyl nitrobenzoate from methyl benzoate‚ using the mixture of nitric and sulfuric acid by performing the process of electrophillic aromatic substitution. During this reaction‚ the combination of HNO3 and H2SO4 made a nitrating solution. The crystallization was done to accomplish pure product. The melting point and Thin Layer Chromatography (TLC) were performed to test the purity of the product. Using

by everyday pollution from houses‚ factories‚ cars‚ and etc. This is the concept of acid rain‚ which according to EPA.gov is a broad term referring to a mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Acid rain isn’t just rain‚ its forms like hail or snow‚ which is wet deposition‚ and smoke or dust‚ which is dry deposition. The effects of acid rain are quite terrifying bringing all types of problems to the Earth‚ for example

Determination of Equilibrium Constants Introduction Bromothymol blue is an indicator for many acid-base titrations. When adding different solutions within the indicator it is to react and change colors‚ in this experiment the different colors were blue‚ green‚ and yellow. In the following experiment‚ obtaining the absorbance levels for each one makes it possible to calculate the equilibrium constant. Materials and Methods For this specific experiment there are a few materials that are crucial

Abstract: In this experiment‚ the methyl nitrobenzoate was prepared from methyl benzoate‚ concentrated HNO3‚ and concentrated H2SO4 via an electrophilic aromatic substitution reaction. The HNO3 and H2SO4 were combined to form a nitrating solution‚ which was mixed with a mixture of methyl benzoate and H2SO4. Percent yield for the final product was calculated followed by recrystallization and melting point was measured. Introduction: Nitration of Methyl Benzoate is one of the examples of
