How does pH change when indigestion tablets work?

When indigestion tablets work, they neutralize the excess stomach acid, leading to a reduction in the acidity level and an increase in the pH of the stomach contents. Here's how it happens:

1. Stomach Acid: During indigestion, the stomach produces excessive hydrochloric acid (HCl), which can cause discomfort, heartburn, and other symptoms associated with acidity.

2. Antacid Ingredients: Indigestion tablets contain antacid ingredients, which are bases or weak acids that can react with and neutralize stomach acid. Common antacid ingredients include calcium carbonate, sodium bicarbonate, magnesium hydroxide, and aluminum hydroxide.

3. Neutralization Reaction: When an antacid tablet is ingested, it dissolves in the stomach, releasing the antacid ingredients. These ingredients react with the hydrochloric acid in the stomach, forming water and salts.

4. Reduction in Acidity: As the antacids neutralize the stomach acid, the acidity level of the stomach contents is reduced. The hydrogen ions (H+) that contribute to acidity are consumed in the neutralization reactions, leading to a decrease in the hydrogen ion concentration.

5. Increased pH: The pH is a measure of the acidity or basicity of a solution, with lower pH values indicating higher acidity and higher pH values indicating lower acidity or alkalinity. As the acidity level decreases due to the neutralization reaction, the pH of the stomach contents increases.

6. Symptom Relief: The increased pH helps to neutralize the acidic environment in the stomach, providing relief from the discomfort and symptoms associated with indigestion.

It's important to note that indigestion tablets are intended for temporary relief of occasional indigestion and should be used according to the recommended dosage and instructions. If indigestion persists or if symptoms are severe, it's advisable to consult a healthcare professional for proper diagnosis and treatment.
