How The Rate Of That Ethanol Produces Ethanal By Potassium Dichromate

KIO3 + 6 HCl + 6 Na2S2O3 → 3 Na2S4O6 + KI +3 H2o + 6 NaCl

In the Cannizaro reaction an aldehyde is simultaneously reduced into its primary alcohol form and also oxidized into it 's carboxylic acid form. The purpose of this experiment is to isolate, purify and identify compounds 1 and 2 which contain 4-chlorobenzaldehyde, methanol, and aqueous potassium hydroxide. Compounds 1 and 2 are purified by crystallization. . The purified product will be characterized by IR spectroscopy and melting point.

During the experiment, two different techniques to disturb systems at chemical equilibrium are utilized. The first one is changing the concentration of one of more species that are involved

(0.074 mol HCl x 1 mol NaOH) / 1 mol HCl = 0.074 mol NaOH

Ethyl ethanoate is made from ethanol and ethanoic acid. In the reaction sulphuric acid is added as a catalyst.

The method used in this experiment is called an oxidation reaction. An oxidizing agent takes away electrons from other reactants during a redox reaction. The oxidizing agent typically takes these electrons for itself, thus gaining electrons and being reduced (Helmstein, Ph. D 2017). The organic oxidant used in this experiment is sodium hypochlorite, which is also known as “household bleach’. Sodium hypochlorite in acetic acid is an alternate oxidizing agent used for the development of ketones that was developed by Stevens, Chapman and Weller due to the many advantages it displays (J. Org. Chem, 1980, 45, 2030). This particular oxidation of sodium hypochlorite is an exothermic reaction meaning that it releases heat as an energy form. Due to the exothermic nature of this experiment, temperature ranges should be monitored throughout the experiment. The overall objective in this experiment is to yield a

Time) because it had a correlation closest to 1. All three orders were graphed and a linear regression was used to see which graphed order was closest to 1. The order was determined by comparing the concentration and time to the mathematical predictions made using the integrated rate laws. Analyzing each graph and finding each correlation helped determine which graph was closest to 1. The more concentrated a solution is, the higher the absorbance of that solution. This is due to Beer’s Law. The law measures the absorbance of a solution by determining how much light passes through a solution. As the concentration of a solution increases, fewer wavelengths of light are able to pass through the concentrated solution. The absorbance at 60 seconds was 0.573 (Figure 1: Table1). To calculate the concentration (molarity), the Beer’s Law equation was used, Abs = slope(m)+b. Plugging in what is known into the Beer’s Law equation resulted in 0.573 = 3.172e+004 + 0, where the concentration is determined by M = 0.573-0/ 3.172e+004. So, the concentration at 60 seconds using the equation (M = 0.573-0 / 3.172e+004) was 1.824e-5 M. The 1st order graph resulted in k=0.006152 (Figure 1: Graph 1). Other groups also resulted in their decolorization of CV to be the 1st rate

The limiting reagent used in this experiment is the isopentyl alcohol while the reagent used in excess is the acetic acid. The molar excess is about 1.5 – 1.75 times greater than the amount that is theoretically yielded.

In the hypothesis it was predicted that the Glucose (C12H12O6) would react with the water in the presence of a catalyst, which would speed up the rate of reaction. In this reaction Glucose would react with water to produce Carbon Dioxide (CO2) and Water (H2O). Methylene blue was an indicator that turned blue as it reacted with the Oxygen in the water. In a perfect case scenario, the dissolved oxygen in the water would cause the Methylene blue to turn blue. As the reaction takes place, the oxygen is consumed in the reaction as glucose is oxidized to form carbon dioxide and water thus, turning the solution colorless. As the flask is mixed, the oxygen is dissolved back into solution therefore converting the color from colorless

The purpose of this lab is to observe the changes in a chemical reaction and how factors affect the system like increase concentrations, temperature, pressure or common ions affect the outcome of the overall reaction and its equilibrium. The Le Chatelier's Principle is used often in order to determine the direction of a reaction, like a balance when disturbed it shifts to more over to one side than the other; in this case if one side of the reaction is stressed the other side will react to counteract for the change. This often means that more or less products will form or reactants will be more present in the end. The five stages performed in this lab with varying chemicals each with stressed the system in various ways. The first reaction is

Experiment 15: Oxidation of Alcohol The purpose of the experiment was to use a computer and the application Excel to record data for the reaction of the oxidation of ethanol to ethanal using potassium dichromate. The reaction was studied. Additionally, a spectrophotometer synced to the computer was used to measure the rate of the reaction.

Ishaan Sangwan Experiment 9: Aldol Condensation Discussion In this experiment, an aldol condensation reaction will be performed using two different carbonyl compounds to form a beta-hydroxy carbonyl compound. Specifically, acetophenone and p-anisaldehyde will react to form trans-p-anisalacetonphenone. An aldol condensation reaction is an addition reaction that consists of one of the carbonyl compounds being converted into an enol or enolate, and attacking the second carbonyl carbon to form a C-C bond. An enol is a hydrocarbon with a double bond, with an alcohol group on one of the double bond carbons.

6CO2 + 6H2O  C6H12O6 + 6O2 (light energy is used as a catalyst in this equation)

In this part of experiment, alcohol(2ml) and CH3COOH(1ml) will react to produce an ester, the ester's odor can then be compared with that of the ester bank to determine the identity of the ester. This is done by mixing the reagents in the solution with a glass stirring rod and then to further dissolve the solution, it
