Determination Of Concentration Of Hydrochloric Acid And Phosphoric Acid

The purpose of this test was to see if there was a presence within Powerade Zero as there was claim that there was no sugar in the drink. This experiment was conducted as Coca Cola had claimed that Powerade Zero contained no sugar. For this test to be effective a comparison was made between Powerade ion 4 and zero .It was expected that there would be no sugar within the sports drink so an experiment was conducted to test the statement.

The purpose of this experiment is to determine an unknown concentration of acid (hydrochloric acid) with a standard solution of a base (sodium carbonate) using titration method.

Acidic Relations in Chemistry is the topic of this experiment. In this experiment, the scientists will be testing the strength of pH and the amount of TDS (total dissolved liquids) in both gunpowder green tea and caffeinated black coffee. The independent variables are the caffeinated beverages and the dependent variables are the pH and TDS levels of the gunpowder green tea and black coffee. The constants are the way we measure the pH and TDS of the caffeinated beverages

The concentration of sugars in two well-known sports drinks, Powerade and Gatorade, were determined by monitoring an enzyme-catalysed reaction sequence involving the appearance of NADPH. Sucrose and glucose concentrations were calculated from the concentration of NADPH formed by the reaction of glucose-6-phosphate and NADP+. Spectrophotometric absorbance readings were taken at 340nm, this is because NADPH absorbs strongly at this wavelength, whilst NADP+ does not (1015MSC, 2010). The concentration of glucose and sucrose in

It was found out that our graphs for yellow 5 and yellow 6 were half the concentrations needed to mimic orang PowerAde. This was found out with the help of the TA. Both the Full Throttle and orange PowerAde used twice as much food dye concentration then what was provided for the experiment. In order to compare our made solution with the beverage, orange PowerAde needs to be diluted to a solution that contained 50% distilled water and 50% PowerAe To do this, take 5 mL of orange PowerAde and add 5 mL of distilled water. A new absorption graph can be formed and used to compare with the made

In this experiment the acetic acid concentration in a sample of Great Value distilled white vinegar, 5% acidity, will be determined in weight percentage and in molarity. The concentration of phosphoric acid in the Unknown solution numbered 86 will also be determined. The equilibrium constants will also be determined for both.

Its concentration was found through a quantitative and qualitative titration testing. Because HCl is acidic, a 1.07M NaOH solution was used to titrate an aqueous solution of HCl (the unknown solution). The PASCO program gave the final results shown in Figure 1. A typical titration curve can be described as starting at the initial pH of the solution, then some acid/base is added, until a sharp curve either up or down takes the pH past a neutral of 7, and towards the pH level of whatever the added acid’s/base’s pH is (Clark6). The stronger the acid or base being titrated, the faster the change occurs, which means a sharper slope of the titration graph. Also, it is important to note the equivalence point on this titration graph. At the equivalence point “the correct amount of standard solution must be added to fully react with the unknown concentration” (Xavier3). In Figure 1, this equivalence point is shown by where the sharpest slope occurs in the curve, which is seen at about a pH of 5.0

General Info- Coke, a soft drink created around 1886, is quickly booming into one of the most recognizable brands in the world. It has spawned dozens of different flavors and merchandise. However, it is a highly acidic substance, with a whopping 2.52 on the pH scale. The lower the pH number, the higher the acidity. This is because of the acids that make up the drink, such as phosphoric acid, added to give a tart flavor and thickness (or viscosity) to the drink.

One milliliter of 6.00-M phosphoric acid was placed into a 125-mL Erlenmeyer flask using a volumetric pipette. Using a slightly larger pipette, six milliliters of 3.00-M sodium hydroxide was transferred into a 50-mL beaker. Then a disposable pipette was used to slowly mix the sodium hydroxide into the phosphoric acid while the solution was swirled around. Then both the beaker and flask were rinsed with 2-mL of deionized water and set aside. A clean and dry evaporating dish was weighed with watch glass on a scale. Then the solution was poured into the dish and the watch glass was placed on top. The solution was then heated with a Bunsen burner to allow for the water to boil off to reveal a dry white solid. After the dish cooled to room temperature it was once again weighed and the new mass was recorded.

By using acid-base titration, we determined the suitability of phenolphthalein and methyl red as acid base indicators. We found that the equivalence point of the titration of hydrochloric acid with sodium hydroxide was not within the ph range of phenolphthalein's color range. The titration of acetic acid with sodium hydroxide resulted in an equivalence point out of the range of methyl red. And the titration of ammonia with hydrochloric acid had an equivalence point that was also out of the range of phenolphthalein.. The methyl red indicator and the phenolphthalein indicator were unsuitable because their pH ranges for their color changes did not cover the equivalence points of the trials in which they were used. However, the

As we all go about our day, we rush to place to place. Around us there are things for sale, people everywhere trying to make money. As we are rushing around, we all tend to get thirsty as we have a thousand things going on. In America we have dozens of choices when it comes to soft drinks, although the two most widely known are Coca-Cola and Pepsi. Many are often stuck between choosing Coke or Pepsi; even though they are slightly different in appearance, taste, and price it makes a world of difference to the customer.

In an industry dominated by two heavyweight contenders, Coke and Pepsi, in fact, between 1996 and 2004 per capita consumption of carbonated soft drinks (CSD) remained between 52 to 54 gallons per year. Consumption grew by an average of 3% per year over the next three decades. Fueling this growth were the increasing availability of CSD, the introduction of diet and flavored varieties, and brand extensions. There is couple of reasons why the industry is so profitable such as market share, availability and diversity and brand name and world class marketing.

Coca Cola’s first main weakness is that it is highly susceptible to any kind of negative publicity. Every kind of negative publicity can hurt the brand badly. Some years ago after traces of pesticides were found in the products of Coca Cola, it had hurt the brand really hard. Sales had dipped in various corners of the world apart from the criticism that flowed. Any such thing can hurt the popularity and sales of coca cola. However, Coca cola can overcome this weakness by being more transparent regarding the ingredients it uses in the production of its brands.

Coca-Cola, a massive global conglomerate, is a deliciously addictive product enjoyed by various Americans. By simply taking a gander at a Coke bottle, the ingredients: carbonated water, sucrose, caramel color, phosphoric acid, natural flavors, caffeine, are anything but healthy or natural. It is evident through this basic observation that many of the extra or ‘waste’ that Coke bottles and factories produce, due to the ingredients,

The industry of Carbonated Soft Drinks (CSD) is highly concentrated. The three major companies, Coca Cola, PepsiCo, and Cadbury Schweppes accounted in 1998 for more than 90% of market share by case volume –Exhibit 1-.
