Answer:
The acid produced when H₂C₂O₄ (oxalic acid) is dissolved in water is also H₂C₂O₄ (oxalic acid).
Step-by-step explanation:
Oxalic acid is a dicarboxylic acid, meaning it has two carboxyl (-COOH) functional groups. When dissolved in water, oxalic acid dissociates into hydrogen ions (H+) and oxalate ions (C2O4 2-). However, because oxalic acid has two ionizable hydrogen atoms, it can donate two hydrogen ions to form two oxalate ions. Therefore, the acid produced when oxalic acid is dissolved in water is still oxalic acid.
