Question

2) Use the following liquid-vapor composition diagram for a mixture of two liquids, Xand Y, to answer the given questions. Give al answers to two significant figures. 80 A. What is the boiling point of pure X? B. What is the boiling point of pure Y? 64 °C 77 °C 75 | For parts C through F, consider a mixture of 0.40 ma of X and 0.60 mol of Y heated to boiling. What is the boiling point of the mixture? the boiling point (assume the vapor is at the same 70 66 °C D. What is the mole percent of X in the vapor phase at temperature as the mixture)? 90% X 0 20 40 60 80 100 E. What would be the mole percent of Xof the first drop collected in a simple distillation? mol % of X F. What would be the mole percent of X of the first drop collected in an ideal fractional distillation? 3) A mixture of water bp 100.0 °C) and nitric acid (b.p. 86.0 °C) forms an azeotrope, boiling at 120.5 °C. A. If the azeotropicmixture is 68% nitric acid by mass, what is the mole percent of water in the azeotrope? B. Fractional distillation of a mass mixture of 10 g water and 10 g nitric acid would yield a distillate with what composition of water and nitric acid? C. Complete separation of the mixture in part B by factional produces a low boiling sample and a high boiling sample. What is the mass and composition of the higher boiling sample?

Explanation / Answer

E  X mole % is 20 and Y is 80% in simple distillation. by looking at graph approxiatmately

F X mole % is 100 in fraction distillation.

3 water and nitric acid mixture come in non-ideal solution

a mole % of water is 62.2%

b if we go mass%, then we have 50% water and 50% HNo3, First Fraction distillate will have arounf 25% of water by mass%

C Low boiling is water and High boiling is azotropic mixture of water and nitric acid with composition 68% of nitric acid.
