Objectives 1. To separate a mixture of an acid and a neutral compound into its component by extraction. 2. To determine the melting point and the yield of the benzoic acid and the unknown sample. 3. To determine the unknown sample whether is is Trimethylmethanol or 1‚2‚4‚5-Tetrachlorobenzene. Introduction Extraction is a process of transferring a solute from one solvent to another. It is usually used to separate one or more components from a mixture. Diethyl ether‚ dichloromethane

Decomposition of Sodium Chlorate Mass‚ Moles‚ and the Chemical Equation Introduction: Sodium chlorate is used as a source of oxygen in emergency oxygen generators. So-called oxygen canisters or oxygen candles are found on airplanes‚ submarines‚ even the space station–anywhere where oxygen might be in short supply in case of an emergency. Sodium chlorate decomposes upon heating or in the presence of metals to give oxygen gas. What the chemical equation for the decomposition of sodium chlorate?

either binary or polyatomic. The simplest compounds to name are binary ionic compounds‚ for example NaCl‚ which is named Sodium Chloride. Na having a positive oxidation number goes first followed by Cl which having a negative oxidation number goes last and is changed from Chlorine to chloride the -ide indicating its negative charge. Of course‚ the

Sodium borohydride Reduction of Benzil Introduction: The Purpose of this experiment is for the students to learn how to use sodium borohydride to reduce benzil to its secondary alcohol product via reduction reaction. This two-step reaction reduces aldehydes by hydrides to primary alcohols‚ and ketones to secondary alcohols. In order for the reaction to occur and to better control the stereochemistry and yield of the product‚ the metal hydride nucleophile of the reducing agents such as LiH‚ LiAlH4

Common Aspects of Acid Prehydrolysis and Steam Explosion for Pretreating Wood Hans E. Grethlein Michigan Biotechnology Institute‚ PO Box 27609‚ Lansing‚ Michigan 48909‚ USA & Alvin O. Converse Thayer School of Engineering‚ Dartmouth College‚ Hanover‚ New Hampshire 03755‚ USA Abstract The initial rate of hydrolysis using cellulase from Trichoderma reesei for various wood samples is directly proportional to the surface area available to the enzyme. Both dilute acid hydrolysis in a continuous

Similar to potassium‚ sodium is a major mineral‚ however‚ unlike potassium which maintains fluid and electrolyte balance inside the cell‚ sodium is a major part of the body’s fluid and electrolyte balance system because it is the chief ion used to maintain the volume of fluid outside cells. Sodium also helps maintain acid-base balance and is essential to muscle contraction and nerve transmission. The DRI recommended intakes for sodium for adults ages 19 to 50 years old is 1‚500 milligrams per day

In this report‚ I will explain what Sulfuric Acid is‚ the health risks and hazards associated with it‚ the safety precautions that should be taken and how the spill should be handled. Sulfuric Acid‚ H2SO4‚ also commonly known as battery acid or vitriol‚ is one of the top products in the chemical industry‚ with 40 million tons produced annually in the U.S. It is a colourless‚ odourless and oily mineral acid that is soluble

Vol. 1 ACETIC ACID 115 ACETIC ACID 1. Introduction Acetic acid [64-19-7]‚ CH3COOH‚ is a corrosive organic acid having a sharp odor‚ burning taste‚ and pernicious blistering properties. It is found in ocean water‚ oilfield brines‚ rain‚ and at trace concentrations in many plant and animal liquids. It is central to all biological energy pathways. Fermentation of fruit and vegetable juices yields 2–12% acetic acid solutions‚ usually called vinegar (qv). Any sugar-containing sap or juice can
