The basic aqueous layer separated previously was then transferred into a 250 mL beaker, and a 50 mL of HCl was collected in a 100 mL beaker. Using a pipette, HCl was slowly added to the basic aqueous substance to acidify it. The lab TA stated that the solution would turn cloudy once acidified, but this did not happen, despite more than 50 drops being added. When the pH was tested, it showed that the pH was definitely 1, despite the solution not being cloudy. The volume of the NaOH and HCl mixture

Steam Distillation is the process of distilling a mixture wherein one of the immiscible phases is a steam. It is a mild method for separating and purifying volatile liquid or solid organic compounds that are immiscible or insoluble in water. This technique is not applicable to substances that react with water, decompose on prolonged contact with steam or hot water, or have a vapor pressure of less than about 5 torr at 100°C. One way to perform steam distillation is through the live steam method
