fractional distillation. Pahlavan EXPERIMENT 7 Distillation Separation of a Mixture Purpose a To purify a compound by separating it from a nonvolatile or le ssvolatile material b To separate a mixture of two miscib le liquids liquids that mix in all proportions with Introduction. The objective of evaporation is to concentrate a solution consisting of . a nonvolatile . solute and a volatile solvent. In the overwhelming majority of . evaporations the . solvent is water.. To relate the boiling point of water to its vapor pressure . Objectives. A. . Evaporation and Vapor Pressure . Vaporization or evaporation . Endothermic . A. . Evaporation and Vapor Pressure . Amount of liquid first decreases then becomes constant . Describe what happens to the particles during this process. Explain why this happens.. Solid to gaseous/vapor form. Vapor to solid. Dry Ice . The Iodine Test. Iodine test: http. ://www.youtube.com/watch?v=4fAOI6BeMZY. Chapter 2. Three States of Matter. Section 1. Identify the three states of matter in this scenario:. You come inside from shoveling some snow. You’re cold, so you make some hot chocolate. You take a sip from the nice, steamy cup, but it burns your lip. You add an ice cube so you can drink it sooner.. 1. Distillation. Simple laboratory distillation. Industrial distillation. Fermentation and distillation. 2. Distillation. How would you separate the yellow liquid from the green mixture?. 3. Distillation. water. ?. How does altitude affect the boiling point of water?. Gather your data. Altitude (. ft. ). Boiling.
