Answer :
Magnesium hydroxide (mg(oh)2) and aluminum hydroxide (al(oh)3) are common ingredients in antacids. when these compounds combine with stomach fluid, which contains hydrochloric acid (hcl), -pH value is 7
Antacids work by inactivating (system is based) acid in the stomach. This is attributable to the fact that the chemical compounds in antacids are bases (alkalis), that are the inverse of acids. The initial response of an acid and a base is known as neutralization reaction. This neutralisation lessens the corrosion rate of the stomach contents.An antacid is a substance that neutralises production of stomach acid and is employed to treat heartburn, indigestion, and stomach upset. Antacid tablets have been used to treat constipation and diahorrea in the past.
