ORGANIC CHEMISTRY LAB 2: Separation of Organic Liquid Mixtures Introduction: In this experiment‚ a mixture of two compounds‚ cyclohexane and toluene‚ was separated into fractions by the techniques of simple and fractional distillation. The individual fractions that were gathered from the distillation were analyzed using gas chromatography (GC) and used to compare the efficiencies of the two different distillation techniques. The ultimate goal of this experiment was to determine whether simple

Determination of Cleansing Action of Detergents (Using Capillary rise) Synopsis This project report explains about the surface tension and capillarity of liquid through a simple experiment of finding the capillarity of various detergents. Oil stains and grease on dirty clothes cannot be removed‚ using water alone‚ because water does not wet them. If detergents added ‚ surface tension is decreased‚ the area of contact is increased

Do all liquids evaporate? What would happen if liquids never evaporated? Do we know which liquid evaporates the fastest? Could we perhaps use this knowledge to change the everyday processes? The process of evaporation happens much differently than scientists once thought. Every liquid eventually evaporates and often what remains is the solid particles which were once part of the solution. Evaporation is very important: “it shapes the climate of the planet‚ it affects the cost of car travel

Lab 2 Report for MATSE 473 Determining Molecular Weight using Solution Viscosity Name: Mengfang Li Group D Lab Partners: Michael Lorenzo‚ Peter Mcclure 01/24/2012 Introduction: This lab was designed to demonstrate the method to measure the intrinsic viscosity of the prepared polystyrene. Intrinsic viscosity‚ which is measured from the flow time of a solution through a simple glass capillary‚ has considerable historical importance for establishing the very existence of polymer molecules

FE 106 GENERAL CHEMISTRY EXPERIMENT-1 DENSITY OF LIQUIDS PREPARED BY BURAK COBAN PURPOSE: In this experiment we will learn how can we find the density of liquids and liquids of density how change effect of temperature‚ pressure‚ mass‚ volume and concentration. For this reason we will take NaCI solutions with different concentrations and we will measure their densities‚ so we will find out the effects of concentration on density of solutions. THEORY:

DISTILLATION ABSTRACT Distillation‚ one of the most significant method for separating a liquid mixture and its components‚ is a process that relies on differences by the ease of vaporization of the components. The purpose of this process is either the separation of a mixture of volatile components from nonvolatile materials is carried out by a simple distillation in which the material is placed to distill and heated‚ the vapor from the substance is removed and condensed. In this activity

Over the last decade‚ drinks containing high amounts of caffeine‚ sugar‚ and other ingredients that increase energy have been rapidly growing in popularity. Clearly these beverages are known as energy drinks. Energy drinks have gotten so popular that it is extremely rare to find a convenience store that doesn’t sell a variety of them. Students use energy drinks to cram the night before a test‚ athletes use them

-1Determination of an Unknown Liquid (2-butanol) Through Fundamental Analysis Lee Billips Department of Chemistry‚ Shippensburg University‚ 1871 Old Main Drive. Shippensburg‚ PA‚ 17257. Abstract: The identification and characterization of unknowns are an important part of organic chemistry. It is fundamental to know experimental methods to deductively identify compounds (1) . The determination of unknown #6 (2-butanol) was identified by a series of test; first taking the boiling point (94-96

some liquids flow more freely than others? Liquids vary in their viscosity (resistance to flow). A definition of viscosity; “Viscosity is a measure of a fluid’s resistance to flow. It describes the internal friction of a moving fluid. A fluid with large viscosity resists motion because its molecular makeup gives it a lot of internal friction. A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion. Gases also have viscosity‚ although
