Alka Seltzer mixture mainly consists of 3 active ingredients; aspirin, citric acid and sodium bicarbonate.
The functions of the following components are as follows;
Aspirin acts a pain reliever and as an anti-inflammatory (which reduces swelling and inflammation). It does this by preventing the action of a substance known as cyclo-oxygenase which produces chemicals in the body.
Sodium hydrogen carbonate and citric acid neutralizes and reduces stomach acid when they react with water. 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

Alka-Seltzer is something that when it gets put into water it has a chemical reaction because it starts to bubble up and when it starts to bubble up the bubbles are carbon dioxide gas. Chemical reactions start when matter is mixed with other matter, you can recognize new compounds by their color or by their acid levels or how a compound looks, feels, or how it acts. Substances create a solid compound. The chemical reaction also happens from more products and properties. They can have one or more products or properties.
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
Goals The primary goal of this experiment was to identify an unknown compound by running various tests to determine the qualitative solubility, conductivity, and pH value of the compound. Tests were also performed for the presence of specific cations and anions in the compound. The second goal was to discover the reactivity of the unknown compound by reacting it with different types of substances. The third goal of this project was to calculate the quantitative solubility of the unknown compound in water.
A buffer solution minimises change in PH of a solution when small amounts of acid or alkali are added to the solution, with an an acidic buffer solutions maintaining a PH<7 (ChemGuide, 2017). It works through an equilibrium, so if the concentration of H+ or OH- are changed, equilibrium will shift to oppose this change and return solution PH to original value. The Alka Seltzer mixture contains an excess amount of the bicarbonate ion which is vital for the buffering action taking place within the solution. This is because the excess bicarbonate ion present, allows the solution to act as a buffer as it’s able to react with small quantities of acids and bases added to the solution, therefore resisting a change in PH by neutralising them.
Citric acid, aspirin and sodium hydrogen carbonate are the main constituents of alka seltzer. Its main role is to reduce headaches, period pains, migraines, muscular pains and symptoms of colds and flues, as well has curing problems related with an upset stomach. Aspirin works to reduce pain and swellings; it is an anti- inflammatory drug and belongs to a group of drugs called NSAIDs as it does not contain steroids. The enzyme cyclo-oxygenase which speeds up the production of prostaglandins is blocked by aspirin.
Problem: How does the temperature of water used to dissolve an Alka-Seltzer tablet affect the amount of time it would take for the tablet to completely dissolve? An Alka-Seltzer tablet is a medicine tablet made with baking soda used as a pain reliever for “headaches, body aches, pain, heartburn, acid indigestion, and sour stomach” (Alka-Seltzer Tablets). It is put into water, left to dissolve and then consumed. When an Alka-Seltzer tablet is dropped into h20, a chemical reaction immediately takes place and produces bubbles made out of carbon dioxide as a product of the collision (Olson 2). When in its original powder (dry) form, the Alka-Seltzer’s two main ingredients: citric acid and sodium bicarbonate are just there and not reacting to each
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.
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.
Carly Herrin American counterculture of the 1960s was one of the most powerful movements that had a lasting influence on American society in the following decades. The counterculture movement is strongly associated with the hippies, sexual revolution, and the protests against Vietnam War. The movement was shaped up by the rejection of the social norms of hippies’ parents but evolved to embrace more specific political and societal goals, including the withdrawal from Vietnam, environmentalism, gender equality, and the expansion of civil liberties. “The Electric Kool-Aid Acid Test” by Tom Wolfe is an excellent non-fiction work that allows to see the movement from the inside and in the specific details of the daily hippie life. Even though the
The Problem: How does temperature affect the dissolving time of an antacid tablet? Antacid tablets are medicines that help neutralize the acid in your stomach. Antacid tablets are made of numerous numbers of components, such as sodium bicarbonate (baking powder), magnesium hydroxide, critic acid, and many others. When Antacid tablets are placed in water, they undergo a chemical reaction, where the sodium bicarbonate breaks apart to make sodium and bicarbonate ions. When the bicarbonate ions collide with hydrogen ions, it produces carbonic acid.
The Medicinal Properties of the Willow Tree Overview The willow tree has been used since ancient civilizations for its ornament, erosion control, timber, and especially its bark. The story of the willow tree dates to Hippocrates, 4000 BC, when people were advised to chew on the bark of a willow tree to lessen inflammation and reduce fever. The bark of the tree contains a compound called salicylic acid, which is a common ingredient in aspirin and is known for a multitude of medicinal effects ranging from something as simple as a pain-reliever to disease prevention. This paper focuses on the history of the willow tree, its anatomy, and its medicinal properties in relation to disease prevention.
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.
Upon cooling, it was shaken until no bubbles were formed. 20 mL of each brand of soft drinks was titrated with NaOH solution. 3 drops of phenolphthalein was used as an indicator if it has already completely reacted. The acidity can then be calculated referring on the known concentration and volume of base; and the known volume of acid.
