Distillation is a technique that is to purify liquid compounds. Explain how distillation is used to separate the target product from any residual unreacted starting material. [2.0 Marks]

Upon completion of the reaction (before filtration), an additional 4.0 mL of 1.0 M NaOH/EtOH was added to the reaction. What was the purpose of this step? Include a chemical reaction as part of your answer. [1 Mark]

The term “side reactions” refers to any chemical reaction that can occur that form products other than the desired product. Side reactions can consume the reactants of your intended reaction, and can affect the percent yield of your target product. Draw the full reaction mechanism for a possible side reaction that can occur under these reaction conditions. Include all charges and intermediates. Vaguely directed arrows will not receive marks.

The following diagram shows a distillation process. Distillation is a technique used in chemistry to purify water from dissolved impurities, mainly salts.

The following diagram shows a distillation process. Distillation is a technique used in chemistry to purify water from dissolved impurities, mainly salts. An example is the conversion of sea water to fresh water as is done in many countries including Oman. Temperature plays an important role in distillation process and the various steps involved are as follows. Step1: Heating impure water to produce steam in the distillation flask. Step2: Steam passes through to the Liebig condenser where it is condensed. Step3: Condensed water...

what are the similarities and differences between distillation, azeotropic distillation, extractive distillation and liquid-liquid extraction.

Q4: Distillation columns are the most commonly used technique for separation purpose in industries. The operating conditions such as temperature, pressure and flowrates are the main factors to ensure that proper separation is taking place inside the column. From your study of distillation column: A. Explain the effects of sudden change, increasing and decreasing of these factors in separation processes. B. Explain the relationship between partial pressure and vapor pressure.
