Which Acid is the Strongest?

What are some acids commonly found in daily life and how do they compare in terms of acidity strength?

Acids in Daily Life

In our daily lives, we often encounter various acids, such as hydrochloric acid, phosphoric acid, nitrous acid, and sulfuric acid. Each of these acids plays a different role and exhibits varying levels of acidity.

Acidity Strength

Hydrochloric acid: Hydrochloric acid is a strong acid commonly found in the stomach to aid digestion. It is highly corrosive and has a pH level of around 1.

Phosphoric acid: Phosphoric acid is commonly used in soft drinks to provide a tangy flavor. It is weaker than hydrochloric acid, with a pH level between 2-3.

Nitrous acid: Nitrous acid is a weak acid that is mainly used in chemical synthesis. It has a pH level of around 3.

Sulfuric acid: Sulfuric acid is known as the "king of chemicals" due to its extensive industrial uses. It is the strongest acid among the four mentioned, with a pH level of around 0.
