Antacid molecules dissociate in the stomach into some R+ group and an OH- group (hydroxide). The hydroxide reacts with an H3O+ ion (hydronium) to form two H2O molecules. The reduction in H3O+ concentration corresponds to increased pH (decreased acidity).
1) ROH -> R+ + OH-
2) OH- + H3O+ -> 2H2O
pH = -ln([H3O+])/ln(10)

What are antaacids?
Antacids are used to neutralize stomach acidity. You take antacids (such as Tums or Rolaids) when you experience heartburn or upset stomach.
Commercials for antacids often claim these products neutralize stomach acid. Antacids are bases. What would be an analogy for the way in which antacids neutralize acids?
An analogy for the way antacids neutralize acids is like adding baking soda to vinegar to produce carbon dioxide gas. In this reaction, the base (baking soda) reacts with the acid (vinegar) to form a neutral product (carbon dioxide). Similarly, antacids neutralize stomach acid by reacting with it to form neutral compounds and reduce acidity in the stomach.
Think of an analogy for the way in which antacids are bases?
Antacids neutralize stomach acid in the same way that a fire extinguisher puts out a fire. Just as the extinguisher counteracts the flames, antacids counterbalance the acidity in the stomach to provide relief from heartburn and indigestion.
Do antacids neutralize stomach acid?
Well actually they reduce stomach acid and it raises the pH to reduce the acidity in the stomach. It also relieves heartburn.
How acidity can be prevented?
Acidity can usually be prevented by antacids.
What happens to the pH of the acid in your stomach when you take an antacid?
The pH of the acid in your stomach increases when you take an antacid. Antacids are alkaline substances that neutralize the excess acid in your stomach, leading to a decrease in acidity.
What salts are in antacids?
Antacids are medicine that counteract acidity. The different types of antacids are sodium antacids (Alka-seltzers), calcium antacids (Tums) and magnesium antacids (Maalox).
What substances can neutralize citric acid?
Substances that can neutralize citric acid include bases such as sodium bicarbonate (baking soda) and calcium carbonate (found in antacids). When these bases react with citric acid, they form water, carbon dioxide, and a salt, which helps to neutralize the acidity of the citric acid.
What do antacids compound have in common?
Antacids typically contain compounds that neutralize stomach acid, such as aluminum hydroxide, magnesium hydroxide, or calcium carbonate. These compounds work by raising the pH of the stomach, reducing acidity and providing relief from heartburn or indigestion.
What describes the pH of an antacid?
Antacids typically have a pH greater than 7, making them alkaline. This alkaline pH helps to neutralize stomach acid and reduce acidity in the digestive system.
How antacids work against bases?
Antacids react with bases and neutralize each other to form a neutral.
Why is carbonate or bicarbonate is common in antacids?
Carbonate and bicarbonate ions in antacids can help neutralize stomach acid by reacting with it to form carbon dioxide and water, reducing the acidity of the stomach. This reaction helps to alleviate symptoms of acid reflux, indigestion, or heartburn. Additionally, carbonate and bicarbonate are relatively safe compounds for consumption and have a long history of use in antacid medications.
