as titration. The titration method involves careful addition of a standard solution that reacts chemically with the substance you wish to quantitate. In this case, you are going to add the antacid to a known amount of acid in solution and determine how much acid is left over by titration with a standard base; sodium hydroxide in this case.
Effectiveness of Antacid Tablets Purpose: The purpose of this experiment is to compare and measure the effectiveness of antacid tablets using an acid titration. Introduction: Different brands of antacids contain a diverse range of active ingredients but all have the purpose of neutralizing excess stomach acid (HCl) by acting as a base.
Dec 26, 2017 · ANTACID. All antacids are bases. A base is any substance that can neutralize an acid. The pH of a base is 7.1-14 (above 7). All antacids have chemical in them called a buffer. When an antacid is mixed with an acid the buffer tries to even out the acidity and that is how stomach acid gets neutralized.
Titration of a Commercial Antacid. Introduction: The parietal cells in the stomach secrete hydrochloric acid (HCl) at a concentration of roughly 0.16 M. The flow of HCl increases when food enters the stomach. If you eat or drink too much, you may develop heartburn or indigestion. Antacids, such as Tums are used to neutralize this excess acid.

Titration is an analytical chemistry technique used to find an unknown concentration of an analyte (the titrand) by reacting it with a known volume and concentration of a standard solution (called the titrant).Titrations are typically used for acid-base reactions and redox reactions. Here’s an example problem determining the concentration of an analyte in an acid-base reaction:
Instead a back titration of base with excess acid will be employed. Why? CO2 gas is released during the chemical reaction and is a slow step. There is a time delay between the addition of the acid and the completion of the reaction. The endpoint of the titration would be unclear because straight titration does not allow enough reaction time.
After all of the antacid has finished reacting with the HCl, you will titrate the remaining HCl with NaOH till the endpoint is reached. Again, you will know the.
