Neutralization Reaction

Eating spicy food can sometimes cause a burning sensation in the stomach. This sensation is caused by excess stomach acid, and an antacid tablet can provide relief.

This is an example of a neutralization reaction, where an acid and a base mix together to create something neutral – usually water and a type of salt.

For example, a neutralization reaction between hydrochloric acid and sodium hydroxide gives sodium chloride and water.

On an ionic level, HCl splits into hydrogen and chloride ions, while NaOH separates into sodium and hydroxide ions.

When mixed, the hydrogen ions combine with hydroxide ions to form water, and sodium ions bond with chloride ions to form table salt, though these remain dissolved in the water solution.

In our stomach, hydrochloric acid helps digest food, but too much of this acid can cause discomfort. Antacids contain bases like calcium carbonate, which reacts with the acid to produce water, calcium chloride, and carbon dioxide gas, giving you relief.

Neutralization reactions are everywhere. They help treat acidic soil in farms, clean spills, and even balance swimming pool water.
