Ответ:
Mg(NO3)2 + 2NaSO3 → Mg(SO3)2 + 2NaNO3
Al(3+) + 3NO3- + 3Na+ + 3OH- = Al(OH)3 + 3Na+ + 3NO3-
Al(3+) + 3OH- = Al(OH)3

1) Mg(NO₃)₂ + Na₂SO₃ → MgSO₃ + 2NaNO₃;
Mg²⁺ + 2NO₃⁻ + 2Na + SO₃²⁻ → MgSO₃ ↓ + 2Na⁺ + 2NO₃⁻;
Mg²⁺ + SO₃²⁻ → MgSO₃ ↓;
2) Al(NO₃)₃ + 3NaOH → Al(OH)₃ + 3NaNO₃;
Al³⁺ + 3NO₃⁻ + 3Na⁺ + 3OH⁻ → Al(OH)₃ ↓ + 3Na⁺ + 3NO₃;
Al³⁺ + 3OH⁻ → Al(OH)₃ ↓.
