To perform this experiment, we will utilize emission spectra, titrations, and thermal gravimetric analysis, using knowledge from Experiments 10, 4, Titrations of Na2CO3 and NAHCO3 by HCl (hydrochloric acid) will be performed to determine the concentration of HCl, as well as the number of moles of HCl present within the sample of baking soda. As a result, we will be able to determine the molar concentration of HCl by determining its equivalence point (the point on the graph where the exact amount of rectant needed to perform a reaction has been added) from graphical analysis. Na2CO3(aq.) + HCl(aq.) ==> NaHCO3(aq.)
It claimed to cure whatever bothered you such as an addition to morphine, headaches, and impotence as well as more. It is also a concentrate which is sold to its bottlers who then add water and bottle it. So Coke is older but both Pepsi and coke are over 100 years old and is just as popular now as they were then. I do not see this changing any time soon. I mean could you image not being able to buy Coca-cola or Pepsi.
Quality Control for Athenium Baking Soda Company Introduction In this experiment, we will be using thermal gravimetric analysis (experiment 4) and HCL titration (experiment 12) to determine the percentage of NaHCO3 (baking soda) in the sample given. We will also be using emission analysis for group IA and IIA salts (experiment 10) to determine the impurities present. The purpose of this experiment is to determine the purity of a sample of baking soda given us by the Athenium Baking Soda Company. We will First determine the percentage of baking soda and then determine whether it contains particulates of CaCl2, LiCl, of KCl for the purpose of seeing whether it is pure and useable or not (the quality of the baking soda). We are performing the experiment to gain our spots on the team of quality control for the Athenium Baking Soda Company.
Explain the phenomenon. Coke is a soda made of ingredients denser than water (such as sugar). However, Diet Coke ingredients (such as its artificial sweeteners) are less dense than water. Because of this, the denser Coke sinks in water while the less dense Diet Coke floats. 4.
Diet Pepsi contains a zero-calorie cola beverage which is an artificial sweetener with aspartame and ace k. Diet Pepsi contains 2.92 mgs of caffeine per fluid ounce (9.86mg/100mls).The ingredients is carbonated water, caramel color, aspartame, phosphoric acid and potassium benzoate so it preserves freshness. It also includes caffeine, citric acid, natural flavor and Acesulfame potassium. The ingredients in regular Pepsi are carbonated water, high Fructose, corn syrup, caramel, color, sugar, phosphoric acid, caffeine, citric acid, natural flavor. Due to the effects of caffeine contained in the Pepsi it may cause alertness and energy. Caffeine is known for awakening the body and causing productivity.
Many people think that diet soda is healthy because diet soda only contains no fat, low or no calories and no sugar. A can of soda can provides 140 calories, whereas a can of diet soda only provides 4 calories. If we switch from a regular soda to a diet soda then we can save up to 146 calories. Therefore some healthy experts recommended to drink diet soda instead of regular soda. In a can of 12 oz diet soda, there are a total fat of 0.7g, no saturated fat, no polyunsaturated fat, no monounsaturated fat, no cholesterol, 28mg of sodium, 25mg of potassium, 0.84g carbohydrate, no dietary fibre, no sugars and 0.39g of protein.
Based on the results, methanol and ethanol exhibit different kinds of intermolecular forces and different vapor pressures. The heat of vaporization (∆Hvap) was found to be 162, which based off of the established value of 37.43, constituted a 332.81% error. Introduction Vapor pressures are an everyday surrounding to us, but many of us do not realize this common occurrence. The simplest way to define vapor pressure is the pressure created by a vapor or gas that forms above a liquid or solid of the same substance.1 Picturing a soda bottle, the bottle itself is pressurized until the hiss sound you hear upon opening the bottle for the very first time. That is the vapor escaping.
Once all the equipment has be gather, step one was to clean the flask because a dirty flask might have an effect on the precise mass of it. To clean the flask, I used distilled water but before I used the water, I had to get the temperature of the water by using a Thermometer according to the experiment guidelines. After getting the temperature, I used the water to clean and then I air dried it. The next side was to weight the empty flask in record the numbers on a weighted scale. After recording the empty flask, I placed the
This wide melting range also indicated impurities. Discussion: The procedure used to isolate the caffeine from a tea bag is very particular. The first step is to submerge the tea bag in hot water, much like when making tea to drink. This separates the soluble fraction from the insoluble cellulose, non-hydrolyzable, and tannins. This step is slightly different from brewing tea because only 10 mL of water is used.
When using Benedict’s reagent, monosaccharides can be identified. Benedict’s reacts with double bonds connected to the oxygen atom in either the free ketone or aldehyde groups (which are the reducing sugars in saccharides) to reduce the copper sulfate in Benedict’s reagent (Harris-Haller 2014). When the substance is heated with Benedict’s reagent, an orange-red precipitate forms within the solution. There were 10 substances in all that we tested for. They were glucose, water, lemon juice, Coca Cola, egg batter, lemon-lime soda, diet lemon-lime soda, Kraft Italian dressing, skim milk and butter.
