Alka-Seltzer is a medical drug that works as a pain reliever and an antacid. The pain reliever used is aspirin and the antacid used is baking soda. When sodium bicarbonate dissolves in water it splits apart into sodium and bicarbonate ions. The bicarbonates reacts with hydrogen ions from citric acid to form carbon dioxide gas and water. This is how the bubbles are made.
The excess bicarbonate however, is responsible for the buffering action of the mixture. This therefore helps in stomach upsets and relieves symptoms of heartburn. The advantages of Alka seltzer are that it is easy to ingest as it dissolves fast due to the components
”(Factors that affect the boiling point of water.) Overall there are many ways that water 's boiling point can be affected by outside forces, but the focus will be on alkaseltzer tablets and how they influence water 's boiling point. The active ingredients in the alka seltzer tablet are “As the tablets dissolve, the sodium bicarbonate splits apart to form sodium and bicarbonate ions. The bicarbonate ions react with hydrogen ions from the citric acid to form carbon dioxide gas (and water). This is how the bubbles are made.
Introduction Alka-Seltzer has been on the market since 1931 and has helped to relieve indigestion and upset stomach. The tablets began to fizz and bubble when dropped into water. “The fizziness happens when baking soda (sodium bicarbonate) and citric acid react chemically in water. They yield sodium citrate, water and carbon dioxide gas, which causes bubbles.” Based on this information, we will measure the reaction time of AlKa- Seltzer dissolved in 200 ml of water at 3 different tempertures in the first portion of this experiment.
This optimizes the sperm survival thus increasing chances of conception. It the ph is too acidic the sperm wont survive which will decrease the chances of
As much was conducted throughout this lab, the projected completion of this lab displays that ultimately, the higher the temperature of the water, the faster the dissolving rate of the Alka-Seltzer is. In other words, the hotter the water temperature the quicker the tablet dissolves within the water in regards to the amount of time it took to dissolve. Furthermore, this experiment helps to explain that, if water is taken at a higher temperature and Alka-Seltzer is placed within the water, the Alka-Seltzer will take less time to dissolve because the higher temperatures cause the tablet to melt at a quicker rate. This compares to when Alka-Seltzer is placed in colder temperatures, where instead it takes more time to dissolve, because the lower
Within the chemical reaction are two different parts, the reactant and product. The reactant, “an initial substance in a chemical reaction” was the alka-seltzer tablets, before they were placed into the water. For instance, when the untouched alka-seltzer was then placed into the water, it formed the product, “the final substance in the chemical reaction” (Tro, 2018). Now, by looking at how the water, or the solvent, dissolved the alka-seltzer tablet, it then created a solute, or a “dissolved substance” (Shuster, 2014). Another example, on a personal level, of a chemical reaction was, whenever I had a sore throat, as a child, my
Q1A: What is the mechanism of action of colistin? Colistin is an antibiotic that works best against Gram-negative bacteria. It works by binding to LPSs (lipopolysaccrides) and phospholipids in the outer cell membrane of the bacteria. This, in turn, disrupts the outer cell membrane by displacing cations and leaking the intracellular contents, combining it with outer cellular contents, causing the bacteria to be unable to differentiate the bacteria’s intra and outer cellular contents from one another.
Many religions use water to purify and cleanse. In the Catholic religion, priests use water to baptize. In the Hindu religion, people use it to cleanse themselves before prayer. Water is often viewed as holy and sacred by these and many other religions, and is commonly associated with life and purity. However, Rudolfo Anaya in his book, Bless Me, Ultima, takes a completely different turn on this commonly used symbol.
Standard Sodium hydroxide solution is the alkaline solution that will be used to titrate with soda water as it is a common solution that can be easily found in an ordinary school laboratory. It is a strong base. Carbonic acid is a weak acid which will react with a strong base to form a basic (pH > 7) solution. When Phenolphthalein is added to Soda water, the resultant solution is colourless. After titration with a strong base (sodium hydroxide), the solution will turn to pink as the solution becomes
Drug addiction is a constant war. It is a battle being fought between oneself, possibly family, friends but always, the drug. Yet for anyone that is struggling, there is hope. Despite our differences, there will always be a path to recovery. In “Water by the Spoonful”, Quiara Alegría Hudes incorporates several strategies and tactics through various character’s agencies and symbolism to ultimately create a piece that centers recuperation.
These qualities of brewing before 1350 are what made brewing the work of almost exclusively women. Bennett uses this example to illustrate that all trades dominated by women were low in status as well, and even though brewing may have shifted to being male dominated, the types of work women performed did not change. As it became more profitable, men tended to take over the trade of brewing. By 1600, brewing had become a hugely commercialized trade.
In his book Everything but the Coffee, Bryant Simon discusses the emergence of Starbucks and how it is able to exemplify the atmosphere of 21st consumer culture. One manner that Starbucks excels is through the powerful meaning behind its name, creating a link between its products and the social issues that Starbucks supports. The power of branding is described by Sarah Banet-Wiser in her chapter Branding Consumer Citizens focusing on the company, Dove. She points to the term commodity activism, or how a consumer is able “to act politically through consumer behavior”, as well as how personal empowerment can result from buying (16). In her example, Dove created a movement to empower young women through the Dove Campaign for Real Beauty.
ABOUT THE SOFT DRINK INDUSTRY: The term "soft drink" refers to all types of nonalcoholic, carbonated, sweetened, flavored beverages. Nonalcoholic soft drink beverage market can be divided into fruit drinks and soft drinks. Soft drinks are available in glass bottles, aluminum cans; PET bottles are disposal containers can be divided into carbonated and non-carbonated drinks. Soft drinks are being manufactured since so long. There are various flavors in soft drinks that are lemon, orange, mango and cola.
DETERMINATION OF PERCENTAGE ETHANOL IN BEVERAGES 1. Introduction to Gas Chromatography Gas chromatography is a very powerful separation technique for compounds that are reasonably volatile. The components of a sample partitions into two phases, the 1st of these phases is a immobile bed with a great surface area, and the other is a gas phase that permeates through the immobile bed. The sample is evaporated and passed by the mobile gas phase or the carrier gas through the column. Samples separates into the stationary liquid phase, based on their solubilities at the given temperature.
