Organic Lab 1: Fractional Distillation Discussion: With the purpose of the experiment being to identify the 30 mL of unknown liquid‚ the theoretical basis of simple and fractional distillation must be deconstructed and applied to the data obtained describing the liquid in question. Simple distillation is a separation technique which can be used to separate and purify distillates from a liquid mixture which ideally contains one volatile and one non-volatile compound. If such ideal conditions are
Premium Distillation Boiling point Temperature
The process of distillation is commonly used to purify liquids. The process of distillation allows separation of distillates based on the temperatures at which they boil. Liquids with higher volatility boil at lower rates than liquids that are less volatile. Because of this when a mixture of two substances is created there will be a spike in the boiling point. At the spike the more volatile substance has vaporized and condense out of the mixture leaving the less volatile liquid. Thus the temperature

FRACTIONAL DISTILLATION October 29‚ 2012 CHEM 210 ME01 INTRODUCTION The process of separating the components of a mixture by distillation into relatively pure fractions is referred to as fractional distillation. Simple distillation‚ a process with similar goals‚ is noted for being a satisfactory attempt at separating two components in an ideal mixture‚ but not as accurate as fractional distillation. To explore these statements further‚ there needs to be an in depth look at the theory that

Lab# 3 – Simple and Fractional Distillation Written by: Theressa Payne Partner: Jennifer Jantzi Performed: February 4‚2013 for CHEM 7005 John Birtwell February 6‚ 2013 Lab # 3 – Simple and Fractional Distillation Introduction: One of the most important tasks in chemistry is the separation of organic compounds which are not usually found in pure form naturally or as products of chemical synthesis. Distillation is a common method for purifying liquids based upon their boiling

f Fractional Distillation of a Solution Results 1. On a single graph‚ plot boiling point versus volume of distillate curves for the two distillations of the cyclohexane/toluene solutions (one from the simple distillation experiment and one from the fractional distillation experiment). The graph is to be computer generated and presentation quality (e.g.‚ appropriately scaled and labeled axes‚ descriptive title‚ and discernable data points). The data points are to be connected with a smooth

I. Introduction Fractional distillation is the separation of a mixture into its fractional parts that entails many concurrent vaporization-condensation cycles. This works because of different boiling points of individual substances. The temperature of the fractional distillation column decreases as its length increases. A higher boiling point component condenses on the column and returns to the solution whereas the lower boiling point component passes through the column and is collected in a receiver

Experiment 1 Cyanobacteria Oxygen Production Through Photosynthesis Date Performed: September 2‚ 2014 I. Introduction a. Background Cyanobacteria or blue green algae are renowned for their tolerability and susceptibility even in wide range of environmental conditions‚ a characteristic of many primitive organisms. CNB are believed to be the agents of autotrophic origin of life thus they probably represent the survivors of the earliest photosynthetic plants‚ along with photosynthetic and chemosynthetic
