White phosphorus on reaction with lime water gives calcium
salt of an acid (A) along with a gas (X). Which of the following is
correct?
White phosphorous + Lime water ⟶
Calcium salt of an acid (A) +Gas (X)
2P4+8Ca(OH)2+6H2O⟶3CaH2PO22+2PH3(X)
(A) is H3PO2 hypophosphorous acid.
(A) is monobasic acid.
2H3PO2 ⟶ Δ H3PO4+PH3
