Answer 2

Acetic acid, Formic acid and Carbonic acid are weak acids.

Explanation:

The acids which produce less hydrogen ions in an aqueous solution are called Weak acids.

• Weak acids partially dissociate in an aqueous solution.
• Strong acids dissociate completely in an aqueous solution.
• The pH range of weak acid lies in between 5 to just below 7.
• Some examples of weak acids are: Acetic acid, Formic acid, Carbonic acid, Bemzoic acid, Oxalic acid, etc.
