Introduction:
The Coca Cola company has advertised the claim that their sports drink, Powerade Zero, contains zero sugar. This claim will be further examined through experimentation to prove whether or it is factual. This will be then compared to Powerade Ion 4 and the amount of glucose which is in the drink will also be determined. To obtain a quantitative measure of how much glucose is present in Powerade Zero and Powerade Ion 4, a spectrometer will be used to measure the colour change from adding Benedict’s to the drinks.
Glucose (C6H12O6) is most common form of sugar, a type of carbohydrate and consists of six carbon atoms, 12 hydrogen atoms and 6 oxygen atoms. During an oxidation process, labelled as metabolism, glucose produces 2870

(Ausetute.com.au, 2016) A redox reaction is a type of chemical reaction which occurs when electrons are transferred between substances during a reaction. The reducing reagent is the substance which causes reduction and therefore loses electrons whereas the oxidising reagent is the substance which causes oxidisation therefore gaining extra electrons. (Chemwiki.ucdavis.edu, 2013) These reactions occur simultaneously with each other however for this to transpire a reducing sugar is …show more content…
This error was that the colorimeter could not produce an accurate measurement of the absorption or concertation as the solutions weren’t filtered enough leading to the large amount of suspended solids in the solutions. To resolve this instead of using filter paper to remove the copper I oxide, a manual centrifuge was used a replacement. By using the centrifuge, the suspended solids were gravitated to the bottom of the test tube therefore the colorimeter could produce an absorption and concertation. To improve this rather than using filter paper to remove precipitates from a solution a centrifuge will be used to remove
Briefly describe an alternative technique that could be used to measure the amount of glucose within sports drinks. (5 points)

For this solution, 5 mL of the solution with 2.5 mL of AMV was placed in the cuvette. The cuvette was placed inside of spectrophotometer and the amount of absorbance was recorded. This procedure that involves a solution with a known concentration was repeated for the concentrations:1.0x10-4 M,5.0x10-5 M,2.0x10-5M, and1.0x10-5M.A unknown solution absorbance was measured by putting 5 mL of unknown solution with 2.5 mL AMV in a cuvette. The cuvette was placed in the spectrophotometer and the amount of absorbance was recorded. The procedure that deals with the unknown solution was repeated 2 more times with the same solution and the same amount of solution and AMV.
Advertisements have become more common and can be found in almost all locations in the society; however they vary depending on the content and the medium they use to convey the information. It can be noted that television has become one of the most influential and powerful medium since it gives both visual and hearing attributes. Television is preferred by many organizations among them being Power ads since it gives a leading hand in competition since it basically influences the consumers not because of the unique product qualities but the mode at which the advertisement is made. Advertisement being one of the marketing strategies has to be designed in a way that it will have an appealing and influential role in the society or in the persons who view the commercial or ad and below is the analysis of the appeals the PowerAde has had in its advertisement as an energy drink. The emotional appeal in any advert should basically have the deep lying desire in which the individuals should be yearning for i.e. the advert should be in such a way that it attracts the attention and increases their quest to gather more knowledge thus increasing the communication.
This report is a business investigation on the Boost Juice business. This report is going to describe the Boost Juice business and its global expansion. It is also going to describe the roles of the business and the ways boost can be classified. The report is also going to explain the internal and external influences that have affected the business.
... samples before the incubation of 108 seconds. Then the 100 µL of colour reagent was put to the sample, merged and incubated for further 10 minutes. The absorbance at 615nm and 700nm wavelengths was calculated on the samples in the Cobas analyser and the sample concentration was measure according to :
Carbohydrates are biomolecules that consist of a chain or ring of carbon atoms attached to hydrogen and oxygen atoms. The simplest formula for carbohydrates is (CH2O)n. Carbohydrates are important to organisms for a variety of reasons. They are used to form the structural components of the cell, aid in energy storage, and serve as intermediary compounds for more complex molecules. Carbohydrates are classified as either monosaccharides, disaccharides, or polysaccharides. Both monosaccharides and disaccharides dissolve easily in water. Carbohydrates are produced in plants through the process of photosynthesis and animals obtain these carbohydrates by eating the plants. ("BIO 1510 Laboratory Manual," 2016)
Sports drinks are used to supplement the loss of electrolytes, water and energy after exercise, helping the athlete recover quicker by replacing the key ionic-substances back into the body. They are designed to give the athlete an equal amount of carbohydrates and fluids to provide an almost instant rehydration and refuel during physical activity. This essay will explain the purpose of the contents of sports drinks and their uses in the human body.
Carbohydrates are categorised in three many groups: Ø Monosaccharide – monomers and therefore contain single surgar. Ø Disaccharide – contain double sugars. Ø Polysaccharide – are large molecules containing many complex sugars. The general formula for carbohydrates is Cx(H20)y. Monosaccharides are white crystalline solids with low molecular mass and sweet tasting.
In order to understand the dangers of sugary drinks and foods, an explanation of their contents is necessary. These drinks and foods are composed of high carbohydrate-content, which is responsible for energy pr...
The materials used in the previous were cleaned and dried. 10ml of CV was obtained along with 10ml of sodium hydroxide. These solutions were separately diluted to 50ml. A stopwatch was set up to record in 30second increments and the Spectrophotometer prepped for the cuvette. The following steps were done within 30seconds. The two solutions (CV and sodium hydroxide) were mixed in a large beaker. A pipette was used to deliver the solution into a test tube serving as the cuvette. The absorbance was recorded every 30second until 15minutes had passed and entered into a spreadsheet. All used materials were cleaned for the next trial.
The Benedict's Test is used to test the presence of simple sugars in a sample. If sugars are present, a color change will occur from blue to red. However, although the Benedict's test shows the presence of sugars, it cannot accurately determine the concentration of sugar in a sample solution. In our method, we added specific concentrations of glucose to the Benedict's test to use as a chart to estimate the glucose concentration of an unknown solution X. Although this gives a rough estimate of the concentration, it is very inaccurate. For example, the mystery solution X was a pale orange color, which was between the colors in my first and second test tube.
Gatorade and Powerade are two common sports drinks. Many people wonder which drink is healthier. Gatorade and Powerade have the same number of calories and sugars. But the type of sugar used in each drink differs. Gatorade uses sucrose, also known as table sugar. On the other

Carbohydrates are the main source of glucose, which is a major fuel for all of the body's cells and the only source of energy for the brain and red cells. Except for fiber, which cannot be digested, both simple and complex carbohydrates are converted into glucose. The glucose is then either used directly to provide energy for the body, or stored in the liver for future use. When a person consumes more calories than the body is using, a portion of the carbohydrates consumed may also be stored in the body as fat.
