The correct statement(s) related to oxoacids of phosphorous is(are):
Upon heating, \( H_3PO_3 \) undergoes disproportionation reaction to produce \( H_3PO_4 \) and \( PH_3 \)
While \( H_3PO_3 \) can act as reducing agent, \( H_3PO_4 \) cannot
\( H_3PO_3 \) is a monobasic acid
The H atom of \( \text{P−H} \) bond in \( H_3PO_3 \) is not ionizable in water
