Extraction and Washing Guide - MIT OpenCourseWare

4) Washing the organic layer to remove impurities. The volume of a wash phase is typically one tenth to one half the volume of the organic phase. It is sometimes best to repeat a wash two or three times. An acid wash (usually 10% HCl) is used to remove amines, while a basic wash (usually sat. NaHCO3 or 10% NaOH) is used to remove unwanted acids.

Definition of Percent Solution | Chegg

For liquid solute, the concentration of the solution can be expressed in terms of volume percent. Example: 1000 mL of a 7.3% by volume of a solution of ethanol in water. It means in 100 mL solution, ethanol is there 7.3 mL. Therefore, in a 1000 mL solution ethanol = 73 mL. Hence 73 mL ethanol and (1000-73) = 927 mL of water is needed.
