Solvent Extraction Using Safe and Commonly Available Materials to Demonstrate the Difference in Solubility of Two Mixed Solutes

Solvent Extraction Using Safe and Commonly Available Materials to Demonstrate the Difference in Solubility of Two Mixed Solutes

A blue, aqueous solution of copper(II) sulfate is mixed with a red ethanolic solution of sudan III forming a purple solution. This mixture is extracted with a nonpolar solvent, resulting in the separation of the red and blue compounds. The nonpolar solvent may be kerosene, vegetable oil, mineral oil...

Description
Summary:A blue, aqueous solution of copper(II) sulfate is mixed with a red ethanolic solution of sudan III forming a purple solution. This mixture is extracted with a nonpolar solvent, resulting in the separation of the red and blue compounds. The nonpolar solvent may be kerosene, vegetable oil, mineral oil, or hexanes. Notes on handling are included.
