Abstract Chemically active extraction was used to separate two unknown compounds from each other and to determine what compound class each compound belongs. The solid unknown was purified by recrystallization and its melting point range was determined to be 109-111°C. The liquid unknown was purified by simple distillation and its boiling point was determined to be 95°C. An IR spectrum was collected for each of the purified compounds; the solid was determined to be 3-toluic acid and the liquid was

Experiment # 8 Qualitative Analysis of Cations Objectives Part I: Separate a mixture of known cations: Pb2+‚ Fe3+‚ Al3+‚ Cu2+‚ and Ca2+ into individual ions. Perform a series of tests to become familiar with reactions characteristic of each cation. Part II: Separate and identify individual cations in an unknown solution containing a mixture of up to five cations. Use information gathered in part I to identify the cations. Introduction Qualitative analysis is a general name for the process

Introduction Longitudinal Qualitative Research is a relatively recent development which has yet to be fully articulated as a coherent methodology (Neale & Flowerdew‚ 2003:189)‚ although examples of this style of research can be traced back several decades. There are few books which deal with it in any depth (although see Saldana‚ 2003). In this essay I am going to; outline longitudinal qualitative research (QLR); address the main features of it; provide an outline of its strengths and weaknesses;

Automated Meter Reading and Load Shed System Problem: A manufacturer of cable TV systems wanted to provide a system that would allow a utility company to be able to read the power meters and control the power consumption (load control) using their cable plant as the communications medium. The system would communicate to a given house through the CATV system and then be sent to the client devices using the home power lines so that no additional wiring would be required. Solution: We developed

PLANT GROWTH EXPERIMENT Numerous environmental variables influence plant growth. Three students each planted a seedling of the same genetic variety in the same type of container with equal amounts of soil from the same source. Their goal was to maximize their seedling’s growth by manipulating environmental conditions. Their data are shown below. Plant Seedling Mass (grams) Day 1 Day 30
