Answer 2

Acetic acid (CH3COOH) and oxalic acid (H2C2O4) are examples of weak acids.
beacuse A weak acid is an acid chemical which does not dissociate (split into ions) completely in water solution. This means it does not give all its hydrogen ions into the water. Weak acids typically have a pH between 3 and 6
