Surfactant Surfactants are also known as ‘surface active agents’. They are usually organic compounds that contain hydrophobic tails and hydrophilic heads. They have wetting‚ emulsifying and dispersing properties‚ which can be used to improve the wetting ability of water‚ break up stains and keep the dirt in the water solution to prevent re-deposition of the dirt onto the surface from which it has just been removed. Surfactant can act as wetting agent as it lowers the surface tension of water.

To separate 4-aminobenzoate into an aqueous layer‚ HCl was added to protonate the NH2 side group and form a salt‚ creating its high solubility in water and low solubility in ether. This allowed the immiscible layers to be distinguished. The addition of NaOH after pouring out the aqueous solution allowed for aminobenzoate to reform from its salt form. However‚ while inverting the funnel to vent before pouring out the layer‚
