Some people have the experience that having
too muchgastric fluid. After seeing a
doctor, they may get the medicine, which is called antacids from doctor. Actually,
how the medicine works is easy. The medicine, which should be a kind of basic
compound just neutralize the hydrogen chloride in your stomach to make you feel
better. In this week, I want to introduce one kind of antacids. It is calcium
carbonate.
(quoted by http://www.bsimedicalsupply.com/Calcium-Carbonate-Chewable-Antacid-assorted-Flavors-MG-150Btl_p_2296.html and http://iizmar.ee/en/portfolio_item/calcium-carbonate/#prettyPhoto)
Calcium carbonate is a weak basic compound with the
chemical formula CaCO3. You can see it in concrete, rock or shell on
animal. In the NTP situation, it is white power or white solid. Besides, it is
hard to dissolve in the water, which is an important property for an antacid.
Being an antacid should be a basic compound to neutralize
the hydrogen chloride. What’s more, it shouldn’t be too basic to prevent from
hurting the esophagus
. Therefore, we sometimes choose a compound, which is not
easy to dissolve in the water. Calcium chloride has both of the properties
above. Therefore, it is common to be used in antacids.
How it reacts? 2HCl(aq)+CaCO3(s)àCaCl2(aq)+CO2(g)+H2O(l)
Sometimes I think I could just eat marble and get the same results……haha
