Determining the pH of Household Items March 22, 2016: Sara, Sam Introduction: Everyday household items can be seen as just “household items”. However, it is often not realized that we could actually determine the pH very easily. It could also be important to know the pH in everyday life. For example, it is important to keep track of human pH levels. Some people are curious to see the pH of their own body, which is a great use to keep acidic levels leveled. Another use in real life is determining

Question: Does the depth of the river affect its overall pH from mid december 2015- to early january 2016? Knowledge Probe: According to.epa.gov/acidrain/measure/pH.html, pH is a measure of the hydrogen ion concentration of a solution. Solutions with a high concentration of hydrogen ions have a low pH and solutions with a low concentrations of H+ ions have a high pH. A pH of 7 is the most neutral you can get and 0 being the most acidic and 14 being the most basic. each level is 10 times more basic/

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
