Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation

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 the methyl benzoate reaction product‚ methyl
