b. Ka Paʻa ʻole a me ka Wehewehe ʻana: He paʻa ʻole maoli ka Rongalite a hiki ke wehe ʻia ma lalo o kekahi mau kūlana:
Ka hoʻokahe wikiwiki ʻana i ka lewa: 2Na₂S₂O₄ + O₂ → 2Na₂SO₄ + 2SO₂↑
Ka hopena o ka Sodium Hydrosulfite i loko o ka hopena wai: 2Na₂S₂O₄ + H₂O → Na₂S₂O₃ + 2NaHSO₃
Ka palaho ʻana i ka ea pulu: 2Na₂S₂O₄ + O₂ + 2H₂O → 4NaHSO₄
Ka palaho wikiwiki ʻana ma nā mahana >90°C: 2Na₂S₂O₄ → Na₂SO₃ + Na₂S₂O₅
Ka hoʻā ʻana a me ke kuni koke ʻana ma nā mahana ma luna o 250°C.
