Answer 2

Explanation:

Oxalic acid turns blue litmus red.

Chemical Formula of Oxalic acid

$\implies{\bold{\mathsf{C_2H_2O_4}}}$

Ph value of oxalic acid:—

$\bigstar$Its Ph value is 1.3 which is acidic in nature.

$\implies$When Oxalic acis is added to an acidic solution, it turns red and when added to a basic solution, it turns blue.

$\implies$This pH paper changes its color in different pH solutions or different natures of solution ,

$\implies$because of the presence of chemical known as flavin, which is an natural pigment present in red cabbage.

$\implies$The change in color as an indication of a pH indicator is caused by the dissociation of the $H^{+}$ ion from the PH indicator
