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...
