Answer:
When solid oxalic acid dissolved in water, it dissociates , H+ - ions is formed, so acidic properties can be observed.
Explanation:
When solid oxalic acid dissolved in water, it dissociates , H+ - ions is formed, so acidic properties can be observed.
C2H2O4 ----> [tex]H^{+}[/tex] + [tex]C_{2}HO_{4}^{-}[/tex]
[tex]C_{2}HO_{4}^{-} ----> H^{+} + C_{2}O_{4}^{2-}[/tex]
When oxalic acid is solid, there are no free moving H+ - ions , so acidic properties can not be observed.
