Antacid

how effective antacids are at neutralizing HCl. This experiment required us to place 3 antacids tablets into 3 Erlenmeyer flasks. Next we were required to add 50.00 mL of 0.500M HCl and five drops of phenolphthalein. Finally, we needed to titrate NaOH into the flasks. Each antacid brand required a different amount of NaOH in order for it to be completely titrated. The data collected from the experiment allowed each group to calculate the cost effectiveness of each brand of antacid. To do so we…

Antacids are essential in science and everyday life. They work to neutralize an acid in a reaction. Antacids are bases and the chemistry definitions of a base vary. A base is defined as a substance that produces OH- ions in solution in the Arrhenius definition. There is also the Bronsted Lowry definition and the Lewis definition. They are defined as the following respectively: a proton acceptor or H+ ion acceptor and an electron pair donor. These terms are used interchangeably to figure out if…

involved in a variety of aspects including industrial, environmental, and biological contexts. Back titration was used to determine the number of moles of HCl acid that were neutralized by a single tablet of several variations of commercial antacids. In theory, the antacid that neutralized the largest number of moles of acid was found to be the most effective. The results attained suggested that the brand Medifirst was the most effective at neutralizing the HCl. However, dosages and side effects…

H2 blockers are proactive in their approach to the reduction of acid reflux, rather than reactive, like antacids. They work to reduce the production of stomach acid, so that the fluids in the stomach already have a higher pH if and when they do leak in to the esophagus. Because this altered stomach fluid is significantly less acidic, it will not have as detrimental…

acid indigestion can be considered if you do not want to take antacids. Generally, as herbal remedies are natural, they are less harmful to our body. It is true that indigestion is becoming a pervasive problem in modern society. You just need to look around to get an indication. If you look at supermarket and drugstore shelves, you can find them filled with antacids. Television or radio commercials have also been heavily promoting antacids as the cure for heartburn. An acid indigestion that…

Acid-Base Case study 1 The acid base balance of the body is mainly regulated by respiratory and renal system together with the body ‘buffer system. For the body to function normally, the hydrogen ion (H+) needs to be concentrated within a narrow range, represented as pH, which determines the acidity and alkalinity of a solution. Changes in the bicarbonate (HCO3) concentration causes metabolic acidosis or metabolic alkalosis while changes in the rate of alveolar ventilation and carbon dioxide…

Before the invention of modern antacids, people would chew chalk (calcium carbonate) to relieve the burning felt by too much acid in the stomach. But most currently used antacids are a combination of aluminum and magnesium hydroxide, often containing sodium bicarbonate as well. The antacids counteract stomach acid by neutralizing the acid, because antacids are formed of bases. Stomach acid, or gastric acid, is made of hydrochloric acid, potassium…

The gastrointestinal tract is significant to proper everyday functions. A large process in this region of the body is gastric acid secretion. This secretion occurs from a number of different mechanisms. However, this process is largely contrived through two means, parietal cells and drugs. Utilized each day in processes like digestion and metabolism, the role parietal cells and drugs play in regulating gastric acid secretion is fundamental to life. Gastric Acid Secretion by Parietal Cells…

The case is about a 22-year-old female who has been sick for eight days. She thought that she had the “Flu”. She complained of nausea, vomiting and had a poor appetite. To counteract her nausea, she was taking copious amounts of antacids. She fell at home and was taken to the ER. She was dehydrated and intravenous fluids were given to rehydrate her. An arterial blood gas (ABG) was drawn. The results of the ABG showed an acid-base disturbance. The patient’s acid-base disturbance was acute…

The number of moles of hydrochloric acid neutralizes for the three trials (2,4,5) were calculated using stoichiometry. It was calculated for trial 2 by convert 4.88 mL NaOH to L by divide by 1000 mL. Then, to get to mol of NaOH the molarity of NaOH was multiplied by 0.00488. Then to get from NaOH to HCl, the mole ratio 2 HCl to 1 mol NaOH was multiplied by 0.00122. To get the amount of HCl per beaker, 100 mL of HCl was divided by 1000 mL to get 0.1 L. Then, the liters were converted to moles by…
