Question

H3 PO2 is not a tribasic acid. Explain​

Answer 1

H3po2

gives basicity according to numbe of (-OH) group attached to phosphorous in its structure thus H-atoms gives reducing character .

As only one (-OH) group is attached to phosphorous atom .

Its is a monobasic acid.

Answer 2

Answer:

H3PO2 ​ gives basicity according to number of (-OH) group attached to phosphorus in its structure thus H-atoms gives reducing character . As only one (-OH) group is attached to phosphorus atom . Its is a monobasic acid.
