Question

P2O5; 2Mg(OH)2; SiO; CuSo4; HNO3; NaCl; H3PO4. С какими из этих веществ реагирует Ca(OH)2??

Answer 1

1. 3Ca(OH)₂ + P₂O₅ = Ca₃(PO₄)₂ + 3H₂O
2. Ca(OH)₂ + Mg(OH)₂ ≠
3. Ca(OH)₂ + SiO₂ = CaSiO₃ + H₂O
4. Ca(OH)₂ + CuSO₄ = CaSO₄ + Cu(OH)₂↓
5. Ca(OH)₂ + 2HNO₃ = Ca(NO₃)₂ + 2H₂O
6. Ca(OH)₂ + NaCl ≠
7. 3Ca(OH)₂ + 2H₃PO₄ = Ca₃(PO₄)₂ + 6H₂O
