Acetic acid

Vedclass · Answer

(D) Calcium oxalate $(CaC_2O_4)$ is a salt of a strong base $(Ca(OH)_2)$ and a weak acid (oxalic acid,$H_2C_2O_4$).It dissolves in strong mineral acids like $HCl$ and $HNO_3$ because the oxalate ions react with $H^+$ ions to form undissociated oxalic acid,shifting the equilibrium forward.Acetic acid $(CH_3COOH)$ is a weak acid and does not provide a sufficiently high concentration of $H^+$ ions to dissolve the precipitate.Therefore,it will not dissolve in acetic acid.
