The sample is titrated with 1.0N HCl at such a rate as to maintain a constant pH of 3.0, while recording on a strip chart the volume of acid used versus time. The titration is continued until no more acid is consumed. The times, in minutes, when 50% (T 50 ) and 90% (T 90 ) of the total antacid are consumed by the acid are determined.
Occasional heartburn is common and generally not serious. However, GERD may lead to esophagitis, an inflammation of the lining of the esophagus (food tube).
Record the brand of antacid in Data Table 2. Magnesium hydroxide (Phillips’ Milk of Magnesia) is fast-acting and relatively long-lasting and reacts with acid according to Equation 4. How will “neutralizing power” be detected? An acid-base indicator, methyl orange, will be added to indicate the loss of “neutralizing power.” Methyl orange indicator undergoes a color change between the pH values of 3.0 (red) and 4.4 (yellow).
Using indigestion tablets to neutralise an acid
The samples are for laboratory use only, have been stored with non-food-grade laboratory chemicals and are not meant for human consumption. Hydrochloric acid solution is toxic by ingestion and inhalation and is corrosive to skin and eyes.
Magnesium Hydroxide [Mg(OH)2] – Magnesium hydroxide is best known as milk of magnesia. Like magnesium citrate or magnesium sulfate, it is an effective laxative. Were it not for its tendency to cause diarrhea, magnesium hydroxide would be the most ideal antacid. To counter the diarrhea effect, most manufacturers add aluminum hydroxide, which is constipating.
This results show that it is possible to use these carbonated clays as effective antacids. The aim of this research was to evaluate the capacity as antacid of hydrothermally modified kaolin with sodium carbonate solutions. The kaolin used is from Guárico State in Venezuela and its ores have previously been characterised. Possible interactions among the modified clays and pepsin enzyme were also determined. The results showed a high capacity of neutralization of HCl from gastric juice by modified kaolin.
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.
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.
