Weak Acid vs Strong Acid
The differences between weak and strong acids are discussed in the table below,
|
Weak Acids |
Strong Acids |
|---|---|
| The acid that does not ionize completely in the aqueous solution is called the Weak Acidss | The acid that ionizes completely in the aqueous solution is called the Strong Acid. |
| The rate of reaction is slower for the weak acids. | The rate of reaction is very fast for the strong acids. |
| For weak acids pH is higher than 3, i.e. it ranges from 3-7. | For strong acid pH is lower than 3, i.e. it ranges from 0-3. |
| Weak acids have covalent bonds. | Strong Acids have ionic bonds. |
| Some examples of weak acids are, CH3COOH, HCOOH, etc. | Some examples of strong acids are, HCl, H2SO4, etc. |
Keep in Mind
- If the Ka and concentration of the solution are known, it is possible to compute the pH of any solution.
- The calculation methods used to determine pH might vary and are predicated on assumptions.
- Making buffer solutions requires the use of weak acids.
- Weak acids have a sour taste, are sticky in consistency, and can cause nose burns when smelled.
- Strong concentrations of weak acids can be destructive and harmful.

Weak Acids
Weak acids as the name suggests are the acid with less acidic characteristics i.e., less concentration of Hydrogen ions. Weak acids are much more useful than strong acids in our daily life, as strong acids are corrosive to touch. All the daily activities involved using of weak acids, from food to cosmetics, and pharmaceuticals to farming, use of weak acids can be seen extensively. In this article, we will learn about weak acids, various examples, characteristics, and their use in various daily activities. Other than that, we will also learn about the acid dissociative constant and pH of weak acids. So, let’s start our journey into the world of acetic acid.
