In case of hydroxides of phosphorus
presence of P—OH / P—O(-) bond refers
to acidic character. So in case of H2PO
2(-) there is only 1 P—O(-) bond. Thus
it has a basicity = 1. Since Na(+) also
has an acidity of 1 and both H3PO
2(conjugate acid) and Na(conjugate
base) are strong acid and base
respectively, both neutralize each other
resulting in a neutral/normal salt.
