Science Lab- Determining the Most Effective Antacid Robby Grewal SNC2D0 Introduction: Heartburn is a form of indigestion by acid digestion it affects many people worldwide. A solution to defeat heartburn is to take an antacid. An antacid is medicine which neutralizes your stomach acidity. In this experiment‚ we will be using three liquid antacids which are Phillips Milk of Magnesia‚ Life Brand Milk of Magnesia and Diovol plus AF and determine which one is the most effective at neutralizing

Laboratory Report The Most Effective Antacid for the Neutralization of the Stomach Author: Kyler L. Gray 11 October 2017 Abstract: Stomach acid builds up can cause irritation and immense pain to individuals. Luckily‚ antacid tablets are readily available and can be found almost anywhere. However‚ because of there ready availability‚ there are many brands with many different effects. This experiment aimed to determine which antacid tablet was the most effective. After experimentation

The purpose of the lab was to measure the effectiveness of antacids at neutralizing excess stomach acid. A neutralization reaction is when an acid and a base react to form water and salt. To illustrate‚ H+ hydrogen ions from the acid react with the hydroxide ions OH- from the base. Antacids are taken to relieve heartburn or indigestion caused by excess stomach acid. For instance‚ antacids such as alka-seltzers contain baking soda which is highly reactive with acids‚ settling the discomfort of indigestion

Formal Lab Report Analysis of Antacid Tablets I. Introduction An acid-base titration is a method of neutralizing strong acids. Unbeknownst to many‚ acid-base titrations occur on a daily basis. Our stomachs use acid to help us digest our food – approximately .155 hydrochloric acid (HCl) with a pH of 2-3. When too much of this acid is formed in the stomach‚ heartburn and other discomfort occurs. This is when people grab for their antacids; these are bases that neutralize the

Which Antacid Works the Best? Heartburn is a condition characterized by a burning feeling in the chest and a sour or bitter taste in the mouth. Heartburn usually develops when the acidic contents of the stomach flow back‚ or regurgitate‚ into the esophagus‚ the muscular tube that carries food from the throat to the stomach. Approximately one in ten adults experience heartburn once a week. Heartburn is more common in pregnant women because of the pressure the expanding uterus exerts on the stomach

ANTACIDS- Classification and Mechanism of Action INTRODUCTION Antacids are defined as a substance‚ generally a base‚ which counteracts stomach acidity. The name antacid means anti-acid (against acid). Antacids are the primary treatment for ailments such as gastric reflux‚ gastritis‚ upset stomach and heartburn. Hydrochloric acid is secreted by the stomach to kill harmful organisms‚ aid digestion and activate digestive enzymes. Excess secretion of acid into stomach or impaired resistance by
