H₂ + 2Na = 2NaH
NaH + H₂O = NaOH + H₂↑
3NaOH + FeCl₃ = Fe(OH)₃↓ + 3NaCl
3Na⁺ + 3OH⁻ + Fe³⁺ + 3Cl⁻ = Fe(OH)₃ + 3Na⁺ + 3Cl⁻
3OH⁻ + Fe³⁺ = Fe(OH)₃
2Na + H2 →(t°) 2NaH
2NaH + O2 → 2NaOH
Fe2(SO4)3 + 6NaOH → 2Fe(OH)3↓ + 3Na2SO4
2Fe³⁺ + 3SO4²⁻ + 6Na⁺ + 6OH⁻ → 2Fe(OH)3↓ + 6Na⁺ + 3SO4²⁻
2Fe³⁺ + 6OH⁻ → 2Fe(OH)3↓
