Introduction: The theory behind the extraction of a solution containing benzoic acid‚ cellulose‚ and methyl orange involves many components pertaining to the fundamental ideas of solubility and polarity. Using the concepts of like dissolving like and acid base reactions‚ a solution of organic acid (benzoic acid)‚ a water soluble compound cellulose‚ and an organic soluble compound methyl orange‚ can be separated and benzoic acid can be isolated by a method of extraction. At the fundamental level

Extraction Report For experience 4c we were supposed to determine which one is the organic layer in three different tubes that has two layers. To determine which is aqueous (water) or organic‚ I used the technique of adding droplets of water to each tube. If the layer is water‚ then the drops of added water will dissolve in the aqueous layer and increase it’s volume. If the added water form droplets or a new layer‚ then it is the organic layer. Tube 1 (water and n-butyl chloride)‚ after adding
