Vedclass · Answer

(D) Ethanol containing small amounts of water is known as rectified spirit. To obtain absolute alcohol (pure ethanol),the water must be removed. Reacting ethanol with $Mg$ metal is the most effective method because $Mg$ reacts with water to form $Mg(OH)_2$ and $H_2$ gas,effectively removing the water content without reacting significantly with the ethanol under controlled conditions. This process is commonly used in the laboratory to prepare absolute alcohol.

Which of the following is the most suitable method to remove small amounts of water from ethanol?
