Electric generating plants transport large amounts of hot water through metal pipes, and oxygen dissolved in the water can cause a major corrosion problem. hydrazine (n2h4) added to the water avoids the problem by reacting with the oxygen: n2h4(aq) + o2(g) → n2(g) + 2 h2o(l) about 4 × 107 kg of hydrazine is produced every year by reacting ammonia with sodium hypochlorite in the raschig process:
