the nitronium ion reaction with the methylbenzoate. 3. Why does water stop the reaction? Water stops the reaction because of Le Châtlier’s principle. Since water is a product‚ when more is added it drives the reaction to the reactant side. More nitric acid is produced‚ which is not a strong enough electrophile to react with methyl benzoate‚ which stopped the reaction. 4. According to your TLC plate‚ how many products did your reaction produce and which isomers are produced? My reaction produced

Objective: The objective of this experiment is to use acid-base extraction techniques to separate a mixture of organic compounds based on acidity and/or basicity. After the three compounds are separated we will recover them into their salt forms and then purify them by recrystallization and identify them by their melting points. Procedure: Extraction of Carboxylic Acid A pre-weighed (0.315g) mixture of Carboxylic acid‚ a phenol‚ and neutral substance was placed into a reaction tube (tube 1)

Introduction This lab’s purpose was to determine whether Salicylic Acid made from methyl salicylate is the same as Salicylic Acid made from benzene. This information can be found by comparing the difference in melting points of the two samples of Salicylic Acid. Here are the physical properties of Salicylic Acid and the mechanism of reactions that occurred in this lab. How Salicylic Acid is derived: Procedure/Results First‚ .26mL of 2.0mmol methyl Salicylate was measured and put

Recommendations 21 References 22 Appendices 22 Abstract This experiment was performed in order to determine the molarity of a solution and the percent by mass of acetic acid‚ CH3COOH in vinegar. Acetic acid is monoprotic and belongs to the carboxyl family of organic compounds. The titration method is used to neutralize the acids by using the standardized sodium hydroxide solution. It reacts with bases which is sodium hydroxide‚ NaOH to form salt and water. The equivalence point of this neutralization

Equilibrium and Acid Base Test Review: May 2012 Things to know: 1. Explain DYNAMIC EQUILIBRIUM. Why does a reaction at equilibrium look like it is NOT reacting? 2. Are all reactions equilibrium reactions? What assumptions do we make when we say that a reaction does NOT take place or that it is UNIDIRECTIONAL and goes 100% to completion 3. Be able to sketch a graph of the following (assuming that you start with all reactants and no products) : a. A reaction that really doesn’t do anything

Investigate the Effect of Acid Rain on Building Materials Question: What is the effect of 6M sulfuric acid (H2SO4) on the corrosion rate of the 3 grams of steel as the amount (number of sprays) of sulfuric acid increases? Variables: Independent variable: the number of sprays of 6M sulfuric acid (0‚ 5‚ 10‚ 15‚ 20‚ 25 times) to observe its effect on the corrosion rate. Each spray will contain about 10mL. Dependent variable: The corrosion rate. It will be calculated by measuring the mass of steel

the copper was back to its elemental state. In the first reaction‚ 0.95 g of pure copper was reacted with 4.0 mL of concentrated nitric acid under the fume hood. The solution was swirled until all of the copper had dissolved. The balanced equation for this reaction is as follows: Cu (s) + 4HNO3 (aq) à Cu(NO3)2 (aq) + 2NO2 (g) + 2H2O (l) When the nitric acid came into contact with the solid copper‚ a brown gas was immediately released into the fume hood. This brown gas was nitrogen dioxide

development is Folic acid‚ which is also known as folacin‚ or folate. This nutrient is essential for the prevention of anemia‚ since it is used to make the extra blood a woman’s body needs during pregnancy. Folic acid deficiency anemia is characterized by red blood cells that are larger than normal when referring to this type of anemia. The red blood cells are also deformed‚ and both their rate of production and their lifespan are diminished (Charlish and Holt 65). Folic acid anemia occurs most often
