1.	At constant pressure, there exhibits a nearly extreme point at zero concentration for one or several of the components this point is called?(a) Tangent pitch(b) Elliptical pitch(c) Parabolic pitch(d) Circular pitchThe question was asked during an interview.Origin of the question is Azeotropic Elements topic in section Azeotropic and Extractive Distillation of Distillation Design
Answer» Right option is (a) Tangent pitch To elaborate: This PHENOMENON is also called a tangent pinch, such MIXTURES are of great PRACTICAL importance, examples of COMMON tangentially zeotropic mixtures are acetone and WATER.
