Chemical Reaction

Introduction The aim of this experiment is to establish the most suitable solvent required for recrystallising acetanilide, and to exhibit the methods of vacuum filtration and recrystallisation. Experimental Method (for selection of a suitable solvent): Four solvents: dichloromethane, methylated sprits, petroleum ether and water were tested to see how appropriate they were for recrystallising acetanilide….

Introduction The task is to alter and record the different temperatures when magnesium ribbon is places hydrochloric acid. Research questions: How will the magnesium ribbon react to the hydrochloric acid? How quickly will the magnesium ribbon react to the hydrochloric acid at different temperatures? Will it be a slower reaction with the ice bath? Will…

Introduction The purpose of this lab was to use the scientific method to identify an unknown solution, based on the reactions (i.e. color changes) of known solutions with indicator solutions. These known solutions contained different types of macromolecules. Each type of macromolecule reacted with at least one indicator solution in a unique way, which allowed…

Introduction The redox reaction in an electrolytic cell is nonspontaneous. Electrical energy is required to induce the electrolysis reaction. An example of an electrolytic cell is shown below, in which molten NaCl is electrolyzed to form liquid sodium and chlorine gas. The sodium ions migrate toward the cathode, where they are reduced to sodium metal….

Introduction Topic: The denaturing of enzymes. Purpose: To further investigate catalysts and enzymes as well as their reactions to temperature change. Problem: How does temperature affect the rate of an enzyme-catalyzed reaction? Research Source 1: http://www.worthington-biochem.com/introbiochem/tempeffects.html Information found: Like the majority of chemical reactions, the rate of an enzyme-catalyzed reaction raises as the temperature elevates….

Abstract A Diels Alder reaction was done during this experiment between anthracene and maleic anhydride via to yield 9, 10-dihydroanthracene-9, 10-α, β-succinic anhydride. Anthracene was the diene and maleic anhydride was the dienophile. Following recrystallization of the product using xylene and vacuum filtration, a percent yield of 39.9% was calculated for the recrystallized product that…
