Antacids are a class of drugs used to treat conditions caused by the acid that is produced by the stomach.The stomach naturally secretes an acid called hydrochloric acid that helps to break down proteins.This acid causes the contents of the stomach to be acidic in nature, with a pH level of 2 or 3 when acid secretion is active. pH levels are a measure of acidity in the stomach the lower the ...
Mar 29, 2017 Hydrochloric acid has been used for leaching in a number of commercial plants. The ore is boiled with hydrochloric acidat some plants with the strong acid, and at others with weak acidone part of strong acid to two parts of water. As compared with sulphuric acid, hydrochloric has the advantage of putting the radium into solution at the start.

carbonate nano particles. The powder of calcium carbonate obtained from cockle shells was dissolved in about 150 gram of concentrated hydrochloric acid. Obtained calcium chloride solution was mixed with 1.5 gram of chitosan, which was dissolved in 3 acetic acid. This mixture was blended with 70
Essentially pure strontium carbonate is recovered from low to medium grade strontium sulfate containing ores by first treating the ore with a hydrochloric acid solution to remove extraneous materials including calcium, magnesium, barium, and iron. The remaining strontium sulfate containing residue is treated with ammonium carbonate to produce insoluble strontium carbonate and soluble ammonium ...

Oct 01, 2020 A lot of people take calcium carbonate for heartburn, and the calcium carbonate dries up the acid in the stomach over time. So not only is the calcium not being absorbed, but it also ends up actually causing heartburn. In my opinion, apple cider vinegar might be a better choice for GERD or heartburn. But, of course, check with your doctor..
