During extractions, it is common to add a dessicant/drying agent (such as magnesium sulfate) to absorb trace amounts of water from the organic layer (e.g., dichloromethane). If you were adding magnesium sulfate to 50 mL of dichloromethane in a 100 mL flask, how much MgSO4 should you add? 1.0 g 0.5 g the smallest amount possible (just enough to be visible) enough to fill the flask halfway the correct amount is determined by observation. MgSO4 is added until the drying agent no longer clumps and there is no visible water floating on the surface

Why are we using this chemicals?(Determination of solubility and soaping number of lipids) Materials: *Fats and oils*Oil solvent (Equal volume 95% ethanol and ether)*0.5 M alcoholic KOH solution*0.05% phenolphthalein solution*0.5 M HCl solution Procedures: Determination of Saponification Number 1) Dissolve 1 g (or 2 mL) of oil in 3 mL of oil solvent and add 25 mL of KOH solution. Put a few boiling stones and boil in the water bath by mixing for 30 minutes.2) Add 3 drops of phenolphthalein to the saponified and brought to room temperature solution and titrate with HCl.3)Titrate 25 mL of KOH solution containing 2 mL of water with HCl for a blank test. Solubility of lipids 1) Record the physical properties of all oils before starting the experiment. Then observe the solubility of the oils in water and organic solvents. Discuss the difference.2) Add 1 mL of water to the oil solutions in ethyl alcohol. Mix vigorously and record your observations in the first second and after 5 minutes.
