For an azeotrope of HCl and water (boiling at 110°C with 20.2% HCl by mass), the composition and boiling point are:
ARandom
BVariable
CEasily separable by simple distillation
DFixed; behaves like a pure substance during distillation
Answer & Solution
Correct answer: D. Fixed; behaves like a pure substance during distillation
At the azeotropic composition, the liquid and vapour have the same composition. Boiling at a single temperature like a pure substance. CANNOT be separated by simple distillation.
