Carboxylic acids D Aldehydes Cl Primary alcohols . Why are ions much more water soluble than neutral molecules? a. Because they […]

Examples of carboxylic acids are shown below. Phenols are a class of organic acids that contain a hydroxyl group bonded to an aryl roup. When a hydrogen atom is removed from benzene, the new group is called a phenyl group. Like the carbonyl group, carboxyl group, etc. , the phenyl group is a partial structure […]

The way buffer does this Is by reacting with the strong acid/base to form a weak acid/base that will barley affect the pH if any effect. Blood is a good example of how buffers work. The pH of blood is around 7. 4 and If It changes by only . 2 It can be enough […]

The Consulting Chemists Institute has been asked to analyse the drug readying of Aspirin to happen out what per centums of acetylsalicylic acid. saccharose. and drug readying. The intent of this experiment was to find the unknown constituent of panacetin. Panacetin contains acetylsalicylic acid. saccharose. and an unknown constituent. Dichloromate reacts with Panacetin to bring […]

Introduction This portion presents a synopsis of the current employment situation, including objectives, scope, and limitations. The importance of the survey which includes the definition of footings and conceptual model is discussed in this text. Additionally, the background of the survey is provided, indicating that students in various areas of Dasmarinas are facing difficulties in […]

Procedure: Obtain 8.5 mL of isoamyl alcohol and 15. 0 mL of acetic acid in a 100-mL round-bottomed flask. Add dropwise 5 mL of concentrated sulfuric acid with boiling chips and reflux for one hour. At the end of the reflux cool the round-bottomed flask in a cold water bath. Pour the contents of the […]

In 1938, Dr. Albert Hoffman accidentally discovered the psychedelic effects of d-Lysergic Acid Diethylamide-25 (LSD). Psychiatrists in the 1950s and 1960s used LSD for analytic psychotherapy, believing it could help patients release repressed material and gain insights into mental illness through self-experimentation. By the late 60s, LSD became popular as a recreational drug. While its […]

This experiment is about the synthesis of 3-nitrobenzaldehyde through nitration. The nitration of benzaldehyde is an example of an electrophilic aromatic substitution reaction, in which a proton of an aromatic ring is replaced by a nitro group. Many aromatic substitution reactions are known to occur when an aromatic substrate is allowed to react with a […]

Here is the abstract: The article examines the compound known as aspirin, which is commonly used for reducing fever and relieving pain. The experiment involves two parts. In the first part, aspirin is produced by combining salicylic acid with acetic anhydride, using phosphoric acid as a catalyst. The second part entails determining the purity of […]

Lecturer (Guest faculty), Department of Botany, Patna Women’s College, Patna University Tomatoes are most widely used vegetable in daily life. Fresh ripe fruits of tomatoes are refreshing appetizing and are consumed raw in salads or after cooking. Unripe fruits are cooked and eaten. Tomatoes are consumed also in the form of juice, paste, ketchup, sauce, […]

pH is the measurement of acidity or alkalinity in the blood. It ranges from 1 to 14, with a pH of 1 indicating extreme acidity and a pH of 14 indicating extreme alkalinity. The optimal blood pH level is approximately 7.4. When the pH falls below 7, it results in excessive acidity which disrupts metabolism […]

Purpose: The purpose of this particular lab was to demonstrate the difference in separation of Benzoic acid in water and Dichloromethane. Also the difference in separation of Benzoic acid in bicarbonate and Dichloromethane. By calculating the partition coefficient for each of these separations, it became clear the differences in the separation of the aqueous and […]

The objective of the experiment was to prepare Benzilic acid by multistep synthesis starting with benzaldehyde. In this setup however, product of the first step, Benzoin, is provided thereby omitting the first step involving the conversion of benzaldehyde. For this experiment, the microscale techniques of reflux, crystallization, and melting-point determination were used. Utilizing these techniques […]

Discovered in 1849 by Marrsson T., lauric acid, or dodecanoic acid, was initially found in Lauraceae seeds but is also commonly present in soaps, vegetable oil, coconut oil, and breast milk. It is a clear, solid compound that does not dissolve in water. Its appearance resembles a white powdery substance. With a chemical formula of […]

Introduction An acid-base titration is a method of neutralizing strong acids. Unbeknownst to many, acid-base titrations occur on a daily basis. Our stomachs use acid to help us digest our food – approximately . 155 hydrochloric acid (HCl) with a pH of 2-3. When too much of this acid is formed in the stomach, heartburn […]

In this experiment, the stereochemistry of 2,3-dibromo-3-phenylpropanoic was found to determine syn or anti addition of bromines. The melting point was 199-203°C and the NMR J values angle is at 167 which both prove the erythro-2,3-dibromo-3-phenylpropanoic. Determination of the Stereochemistry of 2,3-dibromo-3-phenylpropanoic acid. An addition of bromine was added to trans-cinnamic acid and it is […]

Concepts/Application: Writing chemical formulas, writing ionic equations, determining solubility, measuring acidity and basilica. Pre-Lab Discussion A salt is an ionic compound containing positive ions other than H+ and negative ions other than OH-. Most salts will dissociate to some degree when placed in water. In many cases, ions from the salt will react with water […]

The solution was then cooled under a tap water. Followed by adding 0. 48 g of sodium nitrite to the solution and the solution was stirred until the sodium nitrite dissolved. Then, the solution was poured into a 250 ml beaker that contained 7. 5 g of ice and 1. 3 ml of concentrated hydrochloric […]

As the connection of networks and databases increases, the significance of a reliable database management system becomes evident. When selecting the appropriate system, it is important to consider Transaction and Concurrency Control, Recovery and Backup, and Security as key functions. The protection, backup, and security of databases containing valuable company information are essential to prevent […]

The synthesis of several complex organic compounds follows a multistep synthesis. “Multistep synthesis” refers to the process in which the merchandise of one reaction serves as the get downing stuff in the subsequent reaction. The multistep synthesis of benzilic acid begins with a transition benzaldehyde to benzoin through a condensation reaction. The benjamin so oxidizes […]

The word and chemical equation which I have constructed for the experiment is:Calcium + hydrochloric calcium + water + carbonCarbonate acid chloride dioxide.CaCo3 + 2HCL CaCl2 + H2 O + CO2Reactant ProductI chose this reaction because it is easy to control as the production of carbon dioxide being produced can be monitored with ease. Additionally […]
