Formic acid and carbonic acid are weak acids.
Weak acid: An acid that partially dissociates in an aqueous solution is termed weak acid.
Examples, Carbonic acid , Acetic acid, Formic acid , Benzoic acid , etc.
The dissociation of carbonic acid and formic acid can be represented as:
Hence Formic acid and Carbonic acid are weak acids.
Therefore, the given statement is true.
