Acidity is a set of symptoms caused by excess production of acid by the gastric glands of the stomach. Your stomach naturally produces gastric or hydrochloric acid (HCl) to help digest and break down food. Acidity issues arise when there is excess production of this acid due to triggers such as acidic foods, spicy food, alcohol, dehydration and stress. When acidity occurs, the excess acid may move up from your stomach to your esophagus.
The lining of your stomach with a pH of 1 to 3 is designed as such to withstand a high acidic environment.
When we have acidity or heartburn, we are administered a class of medicines known as antacids. They are actually weak bases. As learned in chemistry, when a base is mixed with an acid a neutralization reaction occurs. When antacids are consumed, it creates a chemical reaction in the stomach lowering the acidity and makes the digestive acids less corrosive and damaging.
Most of the common antacids are Sodium Bicarbonate (NaHCO3), Calcium Carbonate (CaCO3), Magnesium Hydroxide (Mg (OH)2), Magnesium Carbonate (MgCO3) and Aluminium Hydroxide Al(OH)3.
The chemical reaction created when Magnesium Hydroxide neutralizes HCI in the stomach and intestine
