    Introduction: A chemical reaction occurs when you mix baking soda and vinegar. The type of reaction that occurs when you mix the two is called a chemical reaction, the chemical property that is used is called reactivity. Some of the evidence that proves that a chemical change is occurring is when you start to hear a sizzle sound and gas starts to be produced. When the gas starts to produce you will see the bubbles start to rise. The two types of matter that are creating this reaction are called…

    I. Abstract The experiment was about using a method of recrystallization to reform benzoic acid and unknown compound, and identifying that compound. The main principle is the polarity and solubility of compound. The compound was dissolved completely with distilled water in hot temperature and reformed back in cold environment. After the experiment, there were up to more than 50% of the compound being recrystallized and the unknown compound had the melting point at 165.2oC. The experiment…

    2.7 Styrene Butadiene Rubber Styrene Butadiene Rubber (SBR) belongs to the synthetic rubbers families that are derived from Styrene and Butadiene.[53] SBR is an aqueous dispersion of (25%) Styrene (CH2=CHC6H5) and (75%) Butadiene (CH2=CH-CH=CH2) copolymer as shown in Figure (2-1). The copolymerization of these two polymers may done by different ways. Mostly they copolymerized in an emulsion process, by dispersing a soap like surface acting agent where the materials are in water solution.[54]…

    Chapter 3 Process description and modeling 3.1 Process Description of Propylene Glycol Production Process The physical properties of propylene glycol are colourless and clear syrupy liquid when exists at room temperature. Besides than in liquid form, it also may exists in vapor form in air. In order to produce a colourless and odourless chemical, propylene glycol (C3H8O2, PG) involve in the reaction of propylene oxide and water. This involve the process of the hydrolysis of propylene oxide…

    Introduction The purpose of this experiment was to understand acid-catalyzed hydration of alkenes through the formation of exo-norborneol from the reaction of Norborene with acid and the excess of water. Acid-catalyzed hydration is useful in removing double and triple bonds; an unsaturated compound becomes reduced to a saturated compound in the presence of the acid catalyst, or water for this experiment. Hydration of alkenes is the result of acid-catalyzed addition of water to a carbon-carbon…

    How does table sugar react with potassium nitrate? Will the ratio between table sugar and potassium nitrate affect the product produced? According to “Smoke Bomb” (2017), smoke bomb is a firework designed to produce smoke when ignited. Smoke bombs are used in various ways such as signalling aircrafts, paintball guns, airsoft guns, military units, self-defence, entertainment and pranks. Smoke bombs was first invented by a British inventor, Robert Yale in 1848. He started by developing…

    The experiment began by weighing 2.0g of acetanilide into a round bottom flask and adding a stir bar. 20ml of glacial acetic acid was added to the flask and was covered with a watch glass. The solution was stirred until the acetanilide was dissolved. The flask was brought to the hood and 7.0g of pyridinium tribromide was added and then stirred for about 30 minutes with a watch glass as a cover. While stirring, 10% sodium bisulfite was added in 1ml increments until the orange/red color…

    • 3 Pages

    Gas chromatography (like any other chromatography) is a separation technique in which the mobile phase is a gas. This technique is applied for the separation of volatile substances. This method separates a mixture into its components and is used to measure the concentration as well as it identifies the components. GC creates a time separation rather than physical separation which means that the components are separated in time. After they are detected, a chromatogram is generated. Each peak in…

    Name Institution Course: Instructor Date of Submission Separation (Liquid-Liquid Extraction) Lab Summary The aim of this lab was to separate a mixture of aniline, benzoic acid, and 1,4-dimethoxybenzene by the method of extraction. In this experiment, 7 ml of the mixture was used instead of 10 ml. A portion of this mixture was transferred to another flask to facilitate cooling. Afterwards, 3.5 ml of 12 M hydrochloric acid was added gradually to the mixture. A sample was obtained at a melting…

    The first portion of this experiment required the synthesis of salicylic acid from wintergreen oil. To begin, a heating block was set on a hotplate and set to 250℃. A reflux apparatus was set up and securely clamped to a support stand, to be used later in order to conduct the heated reflux for reaction. A boiling flask was obtained and into it went 0.01mol (1.521 g) of methyl salicylate and 15 mL of 6M sodium hydroxide including 3 or 4 boiling chips. The reaction was refluxed and heated from 30…
