Question

Stomach acid has a pH of about $2$ . What is the pH of an antacid that is used to neutralize stomach acid?

Answer 1

When extra acid secretion occurs in the stomach, it can cause pain, bloating, loss of appetite, and many other health-related problems. Overproduction of acid can even lead to serious illnesses such as gastric ulcer formation. So how do you control heartburn? This additional acid is neutralized by an antacid (base).

Complete answer:
We know that stomach acid, or stomach acid, is a colorless, colorless liquid produced by the lining of the stomach. It is very acidic and helps break down food for easier digestion. This makes it easier for your body to absorb nutrients as food moves through your digestive tract. pH refers to the assessment of the concentration of hydrogen ions in any solution and indicates how alkaline or acidic those solutions are. The pH scale has a lower limit of one and an upper limit of $14$ . If the pH of the solution is $\;7$ then it is neutral, if more than $\;7$ it is alkaline and less than $\;7$ it is acidic. Normally, the pH of stomach acid is between $1.5$ and $3.5$ . Drugs that neutralize acid in the stomach are called antacids. These tablets contain several ingredients such as calcium, sodium bicarbonate, aluminium and magnesium which act as alkalis or bases to counteract the acid in the stomach and make the pH neutral. Antacids used to treat excess stomach acid are basic and have a pH of approximately $8.2 - 12.5$ .

Note:
All antacids may work in two ways. First, antacids coat the surface of the oesophagus with a layer that keeps acid in the stomach, or second, they release a gel on the surface of the stomach that helps prevent acid from seeping in. in the food tube. . In this way, it can prevent the symptoms of heartburn.
