Vedclass · Answer

(B) Sodium $(Na)$ is a highly reactive alkali metal that reacts vigorously with water to form sodium hydroxide $(NaOH)$ and hydrogen gas $(H_2)$.Because of this property,$Na$ metal is used to remove trace amounts of water from organic solvents like benzene $(C_6H_6)$ or ether,which do not react with sodium.Alcohols react with sodium to form alkoxides,so $Na$ cannot be used to dry alcohols.Ammonia solution contains water,and $Na$ would react with both,making it unsuitable.Therefore,it is specifically used for drying inert organic solvents like benzene.
