Which Antacid Works the Best? Essay

The goal of this experiment was to find out active chemical components in Anacin and Tylenol, using Thin Layer Chromatography technique. This technique uses the difference in the intermolecular forcer and polarity to separate mixtures. Comparing Rf values were then used to determine the active chemical components in the two analgesics. The overall result was that Acetaminophen exists in Tylenol and Acetylsalicylic Acid exists in Anacin.

Aspirin, Caffeine and Salicylamide were extracted from an over-the-counter pain reliever (BC Powder). These components were separated by manipulating their solubilities by adjusting the acidity and basicity of the solution. By doing this, the three components were forced into conjugate acid (or base) forms, causing selective solubility in either an aqueous or organic solvent. These layers were then separated by use of a separation funnel. Once separated, the components extracted were characterized by measuring the melting point and performing a TLC analysis. Also, the recovered aspirin from the first part of the experiment was recrystallized and compared to that of the

Separation and Purification of the Components of an Analgesic Tablet. Cora Bruno, Lab Section E. Aspirin, Caffeine and Acetaminophen were separated from four analgesic tablets of Excedrin using extraction techniques. 5% wt/vol NaHCO3, 4M HCL, ethyl acetate and deionized water were used to separate the three active components. MgSO4 was used to dry each extraction. Aspirin was isolated using a hot water bath and weighed to determine the percent theoretical recovery and the actual percent recovery of aspirin. After separation, Aspirin (ASA), Caffeine (CAF), and Acetaminophen (ACE) were purified and identified using Thin Layer Chromatography (TLC). Standards and purified ASA, CAF, and ACE were spotted on the silica gel (stationary phase) of the

Panacetin is an analgesic (pain reducing) and antipyretic (fever reducing) drug that is sold in drug stores. However, there is a suspicion that this bottle may be counterfeit, not containing the chemicals that it should. Panacetin should be made up of about 50 percent of the unknown component that we previously separated out of Panacetin for testing. We suspect that this unknown compound is either acetanilide or phenacetin, both of which can be toxic to humans. It is very important that this component is

Ever wonder about the chemical makeup of tablets that people take for pain relief? Before a tablet can be successfully made, the limiting and excess reactants must be considered. The limiting reactant will affect the amount of the product that can be made. Another reason why the starting reactants must be determined carefully is to make reduce the amount of the reactant in excess so that reactants are not wasted. This experiment uses an Alka-Seltzer tablet. Alka-Seltzer dissolves in water and is an antacid and a pain reliever1. The Alka-Seltzer tablet has many uses such as relief of headaches, ingestion, heart burns, or even upset stomachs2. The active ingredients in an Alka-Seltzer tablet is aspirin, also known as acetyl-salicylic acid (C8H12O4), citric acid (C6H8O7), and sodium bicarbonate (NaHCO3)2. The aspirin in the Alka-Seltzer tablet helps with pain relief. Because of the acid-base chemistry (Brønsted-Lowry), citric acid and sodium bicarbonate produce O2, which makes the tablet fizz when it is dropped in liquid. The Brønsted-Lowry theory shows how the Brønsted-Lowry acid donates a hydrogen ion while the Brønsted-Lowry base accepts the hydrogen ions3. The remaining NaHCO3 that is in excess post reaction with the citric acid is what is used to neutralize stomach acid which helps relief heart burn2. The problem in

Swallowing is the movement of food from the mouth into the Esophagus. The esophagus secretes mucus and transports the food to the stomach via peristalsis.

The purpose of this lab is to investigate the composition of a compound suspected to be Panacetin, a type of pain-killer. Panacetin is typically made up of sucrose, aspirin, and acetaminophen, but the third component in this experiment is unknown. The unknown component is suspected to be a chemical relative of acetaminophen, either acetanilide or phenacetin. Using techniques such as extraction, evaporation, and filtration, the three components will be isolated based on their solubilities and acid-base properties. Then, the percent composition of Panacetin can be deduced based on the masses of the three dried components. The

Pre-Lab: Analgesic drugs are known for reducing pain, while antiseptic drugs reduce symptoms such as fevers and swelling. However, some of these drugs can reduce both illnesses. To obtain a pure compound in these drugs, the scientist needs to separate the desired compound by taking advantage of the different physical and chemical properties. Such as; different boiling points, melting points and their solubility properties. To do this a chemist can also asses the differences between acidic and basic substances when they are added to water soluble mixtures. Within this current experiment I will asses the

In this lab we were trying to make Maalox. Maalox is an antacid that used to reduce heartburn by raising the Ph of a person’s stomach. In the lab we mixed an acid that forms precipitate. When the two precipitate were mixed, they formed maalox. Fromt the lab I concluded that maalox is a combination of different chemicals that work together to make and acid into a base.

Alka Seltzer is a combination of citric acid, sodium bicarbonate, and aspirin. Why don’t these react with each other in the tablet since sodium bicarbonate reacts with acid in this experiment?

D. If you can only get the brand name drug, and you are allergic to the inactive ingredients in it, then you are out of luck.

An example of a pill with compounds that make it bitter is Aspirin which is taken from the willow bark which contains 0.08 – 12.6% salicin, and is

The build up of stomach acid may cause irritation and excess pain to individuals. Luckily, antacids being a weak base can help relieve the symptoms and pain. Antacids, such as Gelusil, Medi-Firs, Alka Seltzer, and Alcalak are neutralizing agents of acids that become helpful to the human body when heartburn occurs. Heartburn, also known as acid reflux is a common medical issue that occurs when hydrochloric acid (HCl) from the stomach moves backward along the digestive track to the esophagus (located within the throat). This reverse flow of fluids causes a burning sensation due to and possible sour taste that is characteristic of acids [1].

Naproxen (Naprosyn) is a nonsteroidal anti-inflammatory drug (NSAIDs) used to treat joint pain. M.H. was previously prescribed Naproxen to reduce the bilateral wrist pain and associated inflammation. Naproxen is mainly used to reduce inflammation, stiffness, and pain. NSAIDs block the formation of prostaglandins. Prostaglandins are involved in the body’s normal function and inflammatory response. Proteins, Cox-1 and Cox-2, control these prostaglandins. Cox-1 controls the formation of the prostaglandins involved in the normal function of the body’s organs. Cox-2 controls the formation of the prostaglandins involved in the body’s inflammatory response. By preventing the body from producing prostaglandins, NSAIDs reduce swelling and pain.

When you mix Tap water and an Antacid Tablet the results are production of gas. Gas can be harmful and can escape very easily out of a container. The gas will go into the air and will remain there causing the air to be harmful. One safe way to collect this gas is to place a balloon over the container. The gas will rise up and inflate the balloon and the gas will remain sealed in the balloon. This is a safe way to extract the gas as it will make sure none of the gas can escape to harm people.
