Sulphuric acid

reagent was prepared from an aryl halide. The unknown reagent was then reacted with carbon dioxide to form a carboxylic acid. The solid acid was then isolated and recrystallized before the melting point was taken. The precipitate was then dissolved in water and titrated to determine the molecular weight. The melting point and molecular weight were then used to determine the unknown acid obtained from the experiment. 6. Data and Results The product obtained had a melting point of approximately 107 °C

In order to study the kidney 's regulation of plasma volume, osmolality, and pH, the changes in urine flow rate, specific density, and urine pH of adult human subjects were measured. Subjects were assigned one of four beverage options: water, Gatorade, Coke, or nothing. Beverages of different compositions were used to study what effects does fluid intake have on urine volume and composition. Subjects fasted five hours prior to the experiment, in which the subjects were required to void and test their

Is soda really that bad? Time and time again magazines, schools, and television say that sodas are harmful to the body. They go on to scare people to death, by saying that sodas have been linked to obesity. They state that the rising consumption of sugary drinks has been a major contributor to the obesity epidemic (Harvard). They also say, that it is related to kidney damage and cancer (Boyles). In reality, these sodas are not as bad as they have been made out to be, as long as they are drunk in

Abstract: With the emergence of more novel and effective drug therapies, increased importance is being placed upon the methods by which these drugs are being delivered to the body. Different methodologies have been heavily investigated as possible solutions , one of these methods are intelligent or ‘Smart polymeric drug-delivery systems’. “Stimuli responsive” and “self regulating” drug delivery systems have captured the imagination of researchers, in large part because they suggest a means to mimic

find ingredients like taurine as an important component of these beverages. Taurine is found in products like Red Bull and many energy drinks. What is it and where does taurine come from? Taurine is an amino acid that contains sulphur, a molecule that is not found in many proteins. This amino acid helps increase muscle function, aids performance and sports endurance, and helps regulate blood sugar levels, reduce anxiety, and improve cardiac health. Although taurine is found in bull semen or bile, commercial

A heating bath is used in the laboratory to allow the chemical reaction to occur at an elevated temperature around 1000C. The beaker is a glass vessel which contains the chemical solutions for the purpose of coating. It is placed in the electroless bath where the chemicals are being heated up. The glass rod is used to stir the chemical where the magnetic stirrer is not necessary. The tongs are used to lift the bath after the coating is completed. Tri-sodium citrate and thallium acetate are the chemicals

CMIT/MIT: The three-to-one blend of methylchloro-isothiazolinone (CMIT) and methylisothiazolinone (MIT) is commonly used as a biocide in polymer dispersions. CMIT/MIT is a broad-spectrum biocide that works between 3-9 pH. The mode of action for the CMIT/MIT is that it reacts with the cell proteins causing the inhibition of respiration and ATP synthesis (PCIMAG). Isothiazolones first mechanism which is performed in minutes is the swift inhibition of growth and metabolism. This is then tailed by loss

of matter. They thought that it was possible that individual particles made up matter. As you might imagine, it's useful to be able to measure the acidity of solutions. Scientists have come up with the pH scale for determining the concentration of acid in a solution so we can distinguish between solutions with varying acidity. A Chemical reaction is the outcome of two or more elements together results in the formation of a chemical bond between atoms and compound. Chemicals react together

Respiration is the process that takes place in every living cell to make energy available to the body. Energy is vital for us to carry out many life processes such as movement and so respiration in essential to life. During respiration glucose and oxygen are used in a reaction that produces energy and gives out carbon dioxide and water as waste products. Glucose is obtained by digestion of food and oxygen is taken from the air during a process called breathing or ventilation. Pulmonary Ventilation

carbonation will occur when water reacts with carbon dioxide to form a carbonic acid, which can hollow out rocks by breaking them down, leading to cave formations. Purpose: The purpose of this lab is to demonstrate the effects of chemical weathering on zinc. Hypothesis If metal is placed in mixture of acid and water then the amount of rust will increase because the metal will be more exposed to the acid for a period of time with one or the other mixture
