1.	Calcium is generally preferred over sodium to remove traces of water from alcohol.
Answer» Solution :Both these metals should be used to remove moisture from alcohol as they have strong affinity for WATER. However, sodium is NORMALLY not preferred SINCE it also reacts with alcohol and evolves hydrogen gas. On the other hand, CALCIUM has no action with alcohol and its, therefore, preferred over sodium to remove water or moisture from alcohol.
