| Determine the unknown substances and write down the molecular and ionic reaction equations: P → X₁ → X₂ → Na₃PO₄ / \ Ca₃ (P0₄) A1PO₄
1) 4P+5O₂=2P₂O₅
2) P₂O₅+3H₂O=2H₃PO₄
3) H₃PO₄+3NaOH=Na₃PO₄+3H₂O
3H⁺+PO₄3⁻+3Na⁺+3OH⁻=3Na⁺+PO₄3⁻+3H₂O
H⁺+OH⁻=H₂O
4) 2H₃PO₄+3Ca(OH)₂=Ca₃(PO₄)₂+6H₂O
6H⁺2PO₄3⁻+3Ca2⁺+6OH⁻=Ca₃(PO₄)₂+6H₂O
2PO₄3⁻+3Ca2⁺=Ca₃(PO₄)₂
5) H₃PO₄+Al(OH)₃=AlPO₄+3H₂O
3H⁺+PO₄3⁻+Al(OH)₃=AlPO₄+3H₂O
3H⁺+PO₄3⁻+Al(OH)₃=AlPO₄+3H₂O
