Dear teachers: What is the boiling point of a 45% formaldehyde solution at a pressure of 25 kPa (A)?
According to the T-XY diagram, the mixture has no azeotrope at this pressure; the bubble point is -25.5 degrees, and the dew point is 56.4 degrees
What problem? . . . Mixtures don’t have a boiling point
