Hydrobromic acid

The purpose of this investigation was to determine the relationship between pH and water hardness. Water samples from above the Mount Morgan mine site and below the Mount Morgan mine site were also compared. 8.1 Analysis of the Data It was hypothesised that the water sample from above the mine site would be of better water quality than the sample from below the mine site. It was found that this was, in fact, the case. As seen in Table 7.2, the above sample had lower acidity, hardness and conductivity

Why Are My Fish Dying? Lab Jillian Jeffries Cadiz Marine Eco Period 4 November 19’th, 2014 Purpose: The purpose of this lab is to identify the element that is causing the fish in the Halibut tank to die, by testing each variable between both of the identical tanks. Background Information: To truly understand the cause of this awful fish mortality crisis in the HAGS Company, it is essential that we gather all the information we can about the normal living conditions of both the Halibut

Coal seam gas (CSG) is mostly composed of methane and is typically attached to coal underground. This gas is released when pressure on the coal seam is reduced by removing water from the seams (Queensland Government, 2014 ). In order to obtain the gas, wells are drilled into the coal seams, bringing water from the coal seams to the surface. This process reduces pressure and allows the gas to be released (Queensland Government, 2014 ). CSG is an important energy resource in Queensland and production

1. What is hardness and what impact does it have on water quality? Hardness is the amount of dissolved calcium and magnesium in the water. Hardness impacts on water quality throughout the aesthetic acceptability by consumers (meaning the concentration of the calcium and magnesium and other dissolved solids are measureable by the consumers). In addition to, economic and operational considerations (which is controllable throughout the treatment or blending in public drinking water), hard water tends

2 Methodology employed for application of edible coating and shelf life study: 3.2.1 Coating Solution Preparation and Application Dewaxed shellac, oleic acid, morpholine and ammonia in predetermined quantities were dispersed in 100ml distilled water as shown in Table 3.1. The Coating treatment performed named as S1, S2, S3, S4, and S5. Oleic acid is used an emulsifier and antioxidant agent. The other component morpholine as emulsifying agent and ammonia was used to dissolve shellac being insoluble

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
