Alcohol Dehydration Lab Report

The objective of the experiment “Keeping it Liquid” was to figure out what it takes to keep a compound in a liquid form which caused a phase change. A phase change is when a substance changes from one state or phase to another. There are three main phases that normally occur and they are called Evaporation, Deposition, and Melting. Evaporation is where a liquid changes to a gas. An example of evaporation is when water drops form on the glass of a cold drink on a warm day. Deposition is where a gas vapor goes directly into the solid phase without becoming a liquid first. An example of Deposition often occurs on windows during the winter months. While Melting is where a solid turns into a liquid. Melting occurs when ice turn into a liquid when

A breathalyzer is a gadget for evaluating blood liquor content (BAC) from a breath test. The main advantage of installing a breathalyzer which is used to detect the level of a person’s blood alcohol. Additionally, it will quantify the caliber of alcohol in the blood system by betokens of a chemical reaction which is activated by the caliber of ethanol in the breath. Once the contrivance is conventionally calibrated, the results will be profoundly precise.

The thought of alcohol being involved in fatal crashes brings about an emotional response. Recently, there has been a movement based on emotion rather than logic to change a certain drinking and driving law. This involves lowering the Blood Alcohol Content (BAC) from 0.10% to 0.08% nationwide. However, this attention is misdirected. By looking at my personal experiences, statistics, and current laws, it is clear that there is no need for lowering the BAC.

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

Alcohol dehydrations are widely used in many industries to produce alkene. In this experiment 2-methylcyclohexanol was dehydrated to three possible products using phosphoric acid as a catalyst. The main tool for this experiment is the Hickman still. First, Drierite was added to the Hickman still so that any excess water formed during the experiment will be absorbed. It also acted as a boiling stone and addition surface to increase surface area. Next, 0.75 mL of 2-methylcyclohexanol is added to the still and right after 1 mL of phosphoric acid is added. The phosphoric acid (H3PO4) acts as a catalyst in order for the reaction to occur. The mixture is heated up to between 120o Celsius and 160o Celsius. If the temperature goes above 165oC then

Introduction: long ago the government banned the ability to make alcohol. This has caused a huge uproar which then people started to boot legging, as more and more people started to drink in the safety of their own homes. After the government saw how people were protesting this new law, they decided that they should left the ban. Since then people were able to drink in public, which in return has created another issue, now that they are drunk at a bar, how do they get home. Rather than taking the safe option and utilize some of the state and local programs and call a tow truck, the Driver chooses to just drive how drunk. They think that it’s ok, since they do not have their full mind.

The proof (twice the % alcohol) starts at its maximum and goes down (as the alcohol evaporates). If we start with a high concentration of alcohol, we will get the azeotrope (95% alcohol, 5% water) for a while, then the concentration will decrease.

The purpose of this lab was to carry out a dehydration reaction of 2-methylcyclohexanol by heating it in the presence of phosphoric acid and determining which alkene product would be the major product. Methylcyclohexanols were dehydrated in an 85% phosphoric acid mixture to yield the minor and major alkene product by elimination reaction, specifically E1. The alkenes were distilled to separate the major and minor products and gas chromatography was used to analyze the results and accuracy of the experiment. The hypothesis was the major product of the reaction would be the most substituted product. This conclusion was made because of

The dehydration of 2-methyl-2-butanol was performed using sulfuric acid and phosphoric acid in order to synthesize alkene products 2-methyl-1-butene and 2-methyl-2-butene. After carrying out steam distillation to isolate the organic alkenes from aqueous components within the reaction mixture, the purity and characterization of the products were then assessed through various analytical methods including Gas Chromatography (GC), Infrared Radiation (IR) Spectroscopy, and Nuclear Magnetic Resonance (NMR) Imaging. Through the characterization of the final products, it was found that little impurities remained in the final reaction solution and according to the GC, no alcohol remained in the vial after the reaction was complete. The actual yield

that the Mother was consuming alcohol to excess. Indeed, officers with the Hollywood Police found the Mother under the influence of alcohol when summoned to the parties’ Hollywood home when they resided together. Mother has worn a SCRAM alcohol-monitoring device for nearly a year before the final hearing. As such, the Mother has had time to reflect the negative impact of her use of alcohol. By separate handwritten recommendation and order the Mother will submit to hair follicle testing to address the five violation/obstructions identified by the SCRAM device service provider. The parties will shall in the expense of the hair follicle testing with the Father being responsible for 68% and the Mother being responsible for 32%.

In this experiment, the pKa, dissociation constant, of 2-naphthol was determined by measuring the UV-visible absorption spectra of solution of the acid at different pH values.

We could go even depeer in the explanation of metabolism reaction but this is just an

If a nonpolar substance is added to water, then cohesiveness will decline. The tap water held more paperclips because the water was not “wetter” and it stuck the surface a little longer than the soapy water. The soapy water held less paperclips because the water is “wetter” and it did not stick to the surface as much as the tap water. The data supports the hypothesis because when we added the soap to the water it held less paperclip than the tap water. Possible sources of error could have been if the measurements of the water and soap in the container wouldn’t be accurate. The tap water experiment could have had an error because we could have put too much water in the container and made the water for breaking.

The purpose of this experiment is to show how an acid (Coke) can react together with potassium to create a charger for an iPhone. Potassium and acid formed together makes bubbles. With both potassium and acid working together, they will give off energy to the iPhone. Why Coke? Every liquid will be either acidic or basic traits. An acid-base reaction is a chemical reaction that happens between an acid and a base. There are multiple definitions when considering the reaction mechanism when solving problems. Regardless of what the problem is, it’s always a known fact that when using liquid or gaseous reactions, they become less apparent. You want to use Coke because its pH is the acidity of the substance. For an acidity to be

The objective of this experiment is to successfully perform a dehydration of 1-butanol and 2-butanol, also dehydrobromination of 1-bromobutane and 2-bromobutane to form the alkene products 1-butene, trans-2-butene, and cis-2-butene. The dehydration reactions react under and acid-catalysis which follows an E1 mechanism. It was found that dehydration of 1-butanol yielded 3.84% cis-2-butene, 81.83% trans-2-butene, and 14.33% 1-butene, while 2-butanol is unknown due to mechanical issues with the GC machine. For the dehydrobromination, with the addition of a
