Alka-Seltzer is an effervescent antacid and pain reliever owned by Bayer since 1978. First marketed by the Dr. Miles Medicine Company of Elkhart, Indiana, United States, Alka-Seltzer contains three active ingredients: aspirin (acetylsalicylic acid) (ASA), sodium bicarbonate, and anhydrous citric acid. [1] The aspirin is a pain reliever and anti ...
Sodium bicarbonate rocket. A sodium bicarbonate rocket (sometimes called an Alka-Seltzer rocket) is a model rocket fashioned from a 35mm film canister and propelled by the pressure of a gas, often carbon dioxide, generated from the reaction of an acid with sodium bicarbonate. Sodium bicarbonate rockets are often used in science classes to ...
Carbonated water (also known as soda water, bubbly water, sparkling water, fizzy water, club soda, water with gas, in many places as mineral water, or especially in the United States as seltzer or seltzer water) is water containing dissolved carbon dioxide gas, either artificially injected under pressure or occurring due to natural geological processes.
It can be found in the milk minicontainers used with coffee machines. The compound is the product of antacids, such as Alka-Seltzer, when they are dissolved in water. [citation needed] The pH range of a solution of 5 g/100 ml water at 25 °C is 7.5 to 9.0.
The chemical equation of Alka-Seltzer's effervescence is C 6 H 8 O 7 (citric acid) + 3NaHCO 3 → 3H 2 O + 3CO 2 + Na 3 C 6 H 5 O 7 (trisodium citrate). If I add hydrochloric acid to a solution of water and Alka-Seltzer, then is the neutralization chemical equation Na 3 C 6 H 5 O 7 + 3HCl (aq) → C 6 H 8 O 7 + 3NaCl? If so, then how does Alka ...
An antacid is a substance which neutralizes stomach acidity and is used to relieve heartburn, indigestion, or an upset stomach. [1] Some antacids have been used in the treatment of constipation and diarrhea. [2] Marketed antacids contain salts of aluminum, calcium, magnesium, or sodium. [2] Some preparations contain a combination of two salts ...
Speciation of ions refers to the changing concentration of varying forms of an ion as the pH of the solution changes. [1] The ratio of acid, AH and conjugate base, A −, concentrations varies as the difference between the pH and the p Ka varies, in accordance with the Henderson-Hasselbalch equation. The pH of a solution of a monoprotic weak ...
In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical reaction occurs. [1] A chemical mechanism is a theoretical conjecture that tries to describe in detail what takes place at each stage of an overall chemical reaction. The detailed steps of a reaction are not observable in most cases ...
