Oq fosfor olishning Kunkel usuli:
1) NaNH₄HPO₄ → NaPO₃+NH₃+H₂O
2) 2NaPO₃ + SiO₂ → Na₂SiO₃ + P₂O₅
3) P₂O₅+C → P₄+ CO
Soda ishlab chqarishning Solve usuli:
1) 2NH₄Cl+Ca(OH)₂ → 2NH₃ + CaCl₂+2H₂O
2) NH₃+ CO₂+ H₂O → NH₄HCO₃
3) NH₄HCO₃ + NaCl → NaHCO₃+ NH₄Cl
4) NaHCO₃ → Na₂CO₃ + CO₂ + H₂O
Soda ishlab chiqarishning Leblan usuli:
1) 2NaCl + H₂SO₄ → Na₂SO₄+2HCl
2) Na₂SO₄+ 2C → Na₂S + 2CO₂
3) Na₂S + CaCO₃ → Na₂CO₃ + CaS
