(C) The reaction between phosphorus trichloride $(PCl_3)$ and phosphonic acid $(H_3PO_3)$ is given by: $PCl_3 + 3H_3PO_3 \rightarrow 3H_3PO_2Cl + H_3PO_3$ (Note: The standard reaction for the formation of pyrophosphorous acid is $PCl_3 + 3H_3PO_3 \rightarrow 3H_3PO_2Cl + H_3PO_3$ is not the intended path here). Based on the provided image,the reaction is $PCl_3 + H_3PO_3 \rightarrow H_4P_2O_5 + 3HCl$. The product $H_4P_2O_5$ is pyrophosphorous acid. In the structure of pyrophosphorous acid $(H_4P_2O_5)$,there are two $P-OH$ groups. Since only the hydrogen atoms attached to oxygen atoms (in $P-OH$ groups) are ionisable,there are $2$ ionisable hydrogens in the molecule.
