Well look at the formulae........

$"Oxalic acid:"$ $HO_2C-CO_2H$ is a conventional diacid

On the other hand $"barbituric acid....."$ is a carbon diacid

![https://en.wikipedia.org/wiki/Barbituric_acid]( useruploads.socratic.org )

The acidic hydrogens are the METHYLENE protons on the ring, whose conjugate base is stabilized somewhat by the $beta-"diketone"$ .

What is the difference between "oxalic acid""oxalic acid", and "barbituric acid""barbituric acid"?
