Document Summary
Naoh, etc. ) consult pages 21-22 for special conditions. In general, review the structure and properties of common compounds (e. g. solvents). Think about what structural components (e. g. functional groups) having polar functional groups versus it being overall polar. Student conceptual questions contribute to the molecule"s polarity. Exp 3 order of reactants is variable (not always going to be nahco3, then. Exp 3 extraction how do i know if the organic or aqueous layer is on top: consider density, solvent effects, reactions (e. g. deprotonated) . The solubility represents up to how much solute can be dissolved in solvent. In addition to experimental errors where you might have lost mass of your pure solid, consider the choice of solvent and solubility as a contributor to your theoretical percent recovery. The order of separation in chromatography can be influenced by counterpart, then any ratio of both solvents will remain more nonpolar than the stationary phase. Therefore the nonpolar pigments will elute before the polar.
