To Determine which Antacid could Neutralize the most Stomach Acid

While the stomach produces a small amount of acid at all times, it can be stimulated to produce more acid with the presence of food. When a meal is eaten, both hydrogen and chloride ions move from the surrounding blood through the stomach lining into the stomach. Upon reaching the stomach, these ions produce a highly acidic environment. Certain enzymes needed for digestion require this pH in order to be active. HCl also suppresses the growth of bacteria in the stomach and kills a large portion of the bacteria that enter the stomach with the food you eat.

When is the best time to take antacids?

You will first react the antacid tablet with a known amount (volume) of the standardized HCl. Then you

Methyl orange indicator solution is toxic by ingestion. Universal indicator solution is a flammable, alcohol-based solution. Avoid contact of all chemicals with eyes and skin.

These medications promise prompt relief for stomach distress. Too much food, certain types of food, or high levels of stress may cause the stomach to respond with an outpouring of acid.

This experiment shows how you can measure the amount of hydrochloric acid neutralised by one tablet. This is one measure of the effectiveness of the tablet.

Antacids are basic compounds that raise the pH of gastric juice by neutralizing excess hydrochloric acid produced by the stomach mucosa. Table 3 also provides data for Alka-Seltzer ® , a popular combination antacid and pain reliever. You may decide to have students perform titrations on Alka-Seltzer, using perhaps half of a tablet, as well as on other brands of students’ favorite antacids. The endpoint of the titration can be detected when the indicator just turns red and remains red, indicating a pH of 3.0. Solutions of antacids, however, have a tendency to turn red and then as more antacid dissolves, return to the yellow color.

It’s brought on by backflow (reflux) of often acidic stomach contents into the food pipe (esophagus) and is usually felt as a burning sensation behind the breastbone. Use the average moles of HCl neutralized by the tablets and the average mass of the tablets to determine the moles of acid neutralized per gram of tablet (to three significant figures).

2. The aluminum magnesium antacid powder of Claim 1 wherein said anionic species is selected from the group consisting of OH-, Cl-, HCO 3 -, CO 3 –, HSO 4 -, SO 4 –, H 2 PO 4 -, HPO 4 — and PO4–. and the like can be added with mixing to the magnesium-aluminum precipitate to substitute the anion carried by the precipitate with an anion from the added salt.

The principal approach to treatment of GERD is to reduce gastric acidity. There are powerful drugs used to reduce the secretion of acid, which include the histamine2 (H2) receptor antagonists, and the proton pump inhibitors, or PPIs.
