Question

Differentiate between strong acid and weak acid.

Answer 1

Strong acid fully dissociate in solution.
Weak acids simply do not. As a strong acid dissociates it populates the solution with H+ ions, and thus decreases the pH of the solution. ...
The difference between a strong and aweak acid is their ability to dissociate and form H+ ions.

Answer 2

Strong acid and weak acid differ in the extent of ionization.

• An acid is a substance that can donate a proton on ionization.
• Based on the extent of ionization, acids are classified as weak acids and strong acids.
• Strong acids have a high degree of ionization whereas weak acids ionize to a less extent.
• The pH of strong acids is less than that of weak acids.
• Examples of strong acids include hydrochloric acid and sulphuric acid.
• Acetic acid and carbonic acid are weak acids.
