а) 2NH4NO3 + Ca(OH)2 = Ca(NO3)2 + 2NH3↑ + 2H2O
2NH₄⁺ + 2NO₃⁻ + Ca²⁺ + 2OH⁻ = Ca²⁺ + 2NO₃⁻ + 2NH₃↑ + 2H₂O
2NH₄⁺+2OH⁻=2NH₃↑+2H₂O
NH₄⁺+OH⁻ = NH₃+H₂O
б) (NH₄)₂SO₄ + 2KOH = K₂SO₄ + 2NH₃↑ + 2H₂O
2NH₄⁺+SO₄²⁻+2K⁺+2OH⁻ = 2K⁺+SO₄²⁻+2NH₃↑+2H₂O
2NH₄⁺+2OH⁻=2NH₃+2H₂O
NH₄⁺+OH⁻=NH₃↑+H₂O
в) (NH₄)₃PO₄+3NaOH = Na₃PO₄+3NH₃↑+3H₂O
3NH₄⁺+PO₄³⁻+3Na⁺+3OH⁻ = 3Na⁺+PO₄³⁻+3NH₃↑+3H₂O
3NH₄⁺+3OH⁻=3NH₃↑+3H₂O
NH₄⁺+OH⁻=NH₃

4.а) 2NH4NO3 + Ca(OH)2 = Ca(NO3)2 + 2NH3↑ + 2H2O
2NH₄⁺ + 2NO₃⁻ + Ca²⁺ + 2OH⁻ = Ca²⁺ + 2NO₃⁻ + 2NH₃↑ + 2H₂O
2NH₄⁺+2OH⁻=2NH₃↑+2H₂O
NH₄⁺+OH⁻ = NH₃+H₂O
б) (NH₄)₂SO₄ + 2KOH = K₂SO₄ + 2NH₃↑ + 2H₂O
2NH₄⁺+SO₄²⁻+2K⁺+2OH⁻ = 2K⁺+SO₄²⁻+2NH₃↑+2H₂O
2NH₄⁺+2OH⁻=2NH₃+2H₂O
NH₄⁺+OH⁻=NH₃↑+H₂O
в) (NH₄)₃PO₄+3NaOH = Na₃PO₄+3NH₃↑+3H₂O
3NH₄⁺+PO₄³⁻+3Na⁺+3OH⁻ = 3Na⁺+PO₄³⁻+3NH₃↑+3H₂O
3NH₄⁺+3OH⁻=3NH₃↑+3H₂O
NH₄⁺+OH⁻=NH₃↑+H₂O
