What are Strong and Weak Acids?

Strong and weak acids are classified based on their ability to dissociate into H+ ions in an aqueous solution.

Strong Acids

Strong acids completely dissociate into ions when dissolved in water. They release all of their hydrogen ions (H+) in the aqueous solution. Examples of strong acids include: Hydrochloric acid (HCl), Sulfuric acid (H2SO4), Nitric acid (HNO3), etc.

Weak Acids

Weak acids only partially dissociate into ions when dissolved in water. They release only some of their hydrogen ions (H+) in solution. Examples of weak acids include: Acetic acid (CH3COOH), Carbonic acid (H2CO3), Formic acid (HCOOH), etc.

Acid and Base Strength

Acids are substances that can donate protons (H+ ions) to other substances whereas Bases are substances that can accept protons (H⁺ ions) or donate hydroxide ions (OH) to other substances. Acids and bases are further classified as strong or weak, based on the strength of acid and base.

In this article, we will learn about the strength of acids and bases, factors determining their strength, factors affecting their strength, and the calculation of their ionization constant.
