Synthesis of t-pentyl chloride Place 3.0 mL of t-pentanol (2-methyl-2-butanol) in a pre-weighed 15-mL screw cap centrifuge tube (remember to determine the exact mass of the t-pentanol).Before adding hydrochloric acid to the t-pentanol, make a prediction about whether the
Why is NaCl added to soap? The addition of salt (sodium chloride) to the crude form of soap forms fatty-acid salts. The sodium ions from the sodium chloride bond with the fatty acid, forming a product that is less soluble in water. Because of this reduced solubility, the soap leaves the solution and forms a solid mass.
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.
