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

------------------------------------------------- Liquid–liquid extraction From Wikipedia‚ the free encyclopedia Liquid–liquid extraction also known as solvent extraction and partitioning‚ is a method to separate compounds based on their relative solubilities in two different immiscible liquids‚ usually water and an organic solvent. It is an extraction of a substance from one liquid into another liquid phase. Liquid–liquid extraction is a basic technique in chemical laboratories‚ where it is performed

Jaguar is the upper middle class and high class consumers aged from their mid-thirties to sixties. They target both male and female customers who want the appearance of being well off and extravagant. The apparent demographic target for the Chevy Cobalt is males and females that belong to Generation Y (the generation born in the 1980’s and 1990’s)‚ as well as the working class and middle class‚ as the car is considered affordable. The possible demographic target for McDonald’s is basically the

to be a transition metal‚ no other metal. The sulfates had more transition atoms going through the chemical‚ more than an original transition atom normally. Doing this showed me also that iron nitrate is an transition metal as well‚ same with the cobalt‚ copper‚ and zinc nitrate. (5 points) Score 3. Were there any metallic compounds that did not react with either the acid or the base? Write the type of metal‚ based on your examination of the periodic table. Answer: The alkakine metals seem

Murder mysteries streaming through the nation’s television channels have become a source of entertainment for some individuals; however‚ the officers that discovered the body of a local business man near Robins‚ NC were faced with the reality. The man’s cause of death was listed as drowning because he had a large amount of water located in his lungs. The water in the man’s lungs had a high concentration of phosphates. By analyzing water samples from Woodlake‚ Seven Lakes‚ Reservoir Park‚ and Lake
