In the world of chemistry and biology, understanding the pH level is crucial when discussing substances like antacids. The pH scale measures how acidic or basic a solution is. It ranges from 0 to 14. Substances with a pH less than 7 are considered acidic, while those with a pH greater than 7 are basic, and a pH around 7 is neutral.
In the context of the stomach and antacids, the pH level is a key player. Normally, stomach acid has a very low pH, typically around 1.5 to 3.5, meaning it is highly acidic. This acidity helps in food digestion and protection against pathogens. However, when the stomach produces too much acid, discomfort occurs, leading to conditions like heartburn or indigestion.
- Antacids function by increasing the pH level in the stomach, making it less acidic.
- They achieve this by containing alkaline substances that neutralize stomach acid.
- This action provides fast relief from discomfort and pain due to excess stomach acid.
