Before hydrazine came into use to remove dissolved oxygen in the water in steam boilers, Na 2
Question:
Before hydrazine came into use to remove dissolved oxygen in the water in steam boilers, Na2SO3 was commonly used for this purpose:
2 Na2SO3(aq) + O2(aq) → 2 Na2SO4(aq)
What mass of Na2SO3 is required to remove O2 from 3.00 × 104 L of water as outlined in Study Question 65?
Data given in Question 65
A major use of hydrazine, N2H4, is in steam boilers in power plants.
(a) The reaction of hydrazine with O2 dissolved in water gives N2 and water. Write a balanced equation for this reaction.
(b) O2 dissolves in water to the extent of 0.0044 g in 100. mL of water at 20°C. What mass of N2H4 is needed to consume all of the dissolved O2 in 3.00 × 104 L of water (enough to fill a small swimming pool)?
