neutralization
Calcium carbonate is for neutralising the excess of acid in the stomach.
The safest one is magnesium carbonate. Although alkalis will neutralise acids, they will do damage to the human anatomy, so don't use alkalis. Magnesium carbonate is the active constituent of 'Alka-Seltzer' or 'Milk of Magnesia'. Magnesium carbonate is a chemical salt. Remember all carbonates react with acids to form another salt, water and carbon dioxide. The stomach acid is Hydrochloric Acid which magnesium carbonate will neutralise. Here is the equation. 2HCl + MgCO3 = MgCl2 + H2O + CO2(The burp). Calcium carbonate can be used, but the taste is very chalky.
Sodium bi-carbonate, other wise known as sodium hydrogen carbonate, or baking soda. When the stomach makes too much acid, from overeating, refluxing/heartburn can occur. The stomach naturally makes hydrochloric acid as part of the normal digestion process. However, if you vomit or reflux, that horrible burning sensation in the mouth or throat is hydrochloric acid. Chemically , when you react a carbonate with an acid its products are a 'salt', plus water plus carbon dioxide. So in ingesting sodium bicarbonate it reacts with the stomach acid, to form the 'salt' plus water , plus carbon dioxide (The burp!!!! Here is the chemical equation. HCl(aq) + NaHCO3(aq) = NaCl(aq) + H2O(l) + CO2(g). however the human organism does NOT like too much salt (NaCl), so a better remedy is magnesium carbonate or calcium carbonate. The resultant magnesium chloride or calcium chloride are less harmful to the human organism. However, in taking magnesium carbonate or calcium carbonate, they have a horrible chalky taste, but do the job. Magnesium carbonate is sold as 'milk of magnesia', this also contains magnesium hydroxide (Mg(OH)2).
Limestone or calcium carbonate (CaCO3) is used in antacids to relieve heartburn and indigestion by neutralizing the acid in your stomach.
Antacids are weak bases such as sodium bicarbonate, aluminum hydroxide, calcium carbonate, and magnesium hydroxide. They neutralize acids by reacting with them to produce such products as harmless salts, water, and carbon dioxide.
CaCO3 + 2HCl -> CaCl2 + H2O + CO2
Bone fragments are made of calcium carbonate. When calcium carbonate is eaten and enters the stomach, the acids in the stomach will dissolve the calcium carbonate.
Calcium carbonate is for neutralising the excess of acid in the stomach.
It can neutralize stomach acid (Heartburn)
base.
Calciun Carbonate and Calcium Citrate are different in that, Carbonate is not as easy to absorb as Citrate. Carbonate in not recommended for elderly folks due to a decrease in stomach acids. Citrate in more easily absorbed and can be taken at anytime, with or without food.
Tums, it contains calcium carbonate
Caluim carbonate + Hydrochloric acid = Carcon dioxide + Calicum chloride + water
Calcium Hydroxide (Alkali in the stomach) and Gastric Acid (in the stomach)
The very structure of the molecule of Calcium Carbonate CaCO3means that it contains one Calcium (Ca++) atom, one of carbon (C+), and three of Oxygen (O++). According to the rules of chemical equations, when you mix CaCO3 with HCl (Hydrochloric Acid) found in your stomach, you get Calcium Chloride, Water and Gas CO2. This leaves the acid neutralized, and thus it takes away the burning, as the stomach is no longer trying to digest itself. However, there are better ways of reducing indigestion, as neutralizing your stomach acid, also means that you can't digest protein.
Calcium usually exists as calcium carbonate in pill form and when this compound reacts with the acids in your stomach, carbon dioxide is released. That CO2 is your gas.
Sodium hydrogen carbonate is another name for sodium bicarbonate, which has the chemical formula NaHCO3. Stomach acid is hydrochloric acid that reacts with sodium bicarbonate in a chemical reaction to neutralize stomach acid. The chemical equation is HCl + NaHCO3 produces NaCl + CO2 + H2O.
