A newly developed method for water treatment uses chlorine dioxide, ClO₂ rather than Cl₂ itself. ClO₂ can be obtained by passing Cl₂(g) into concentrated solution of sodium chlorite, NaClO₂. NaCl is the other product. If this reaction has a 90% yield, how many moles of ClO₂ are produced from 5 l of 2.0 M - NaClO₂?
Answer:
9.00
Solution:
Cl₂ + 2NaClO₂ 2ClO₂ + 2NaCl, so 1 mol NaClO₂ gives 1 mol ClO₂. NaClO₂ = 5 × 2.0 = 10 mol, giving 10 mol ClO₂ at 100%. At 90% yield: 10 × 0.9 = 9 mol. Ans: 9.
