The dehydration agent mentioned in the material is?

Explanation:
Alcohol is the dehydration agent because, in tissue processing, the goal is to remove water from the fixed tissue so it can be cleared and infiltrated with paraffin. Ethanol (a common alcohol) is used in a graded series to gradually replace water, and it is miscible with both water and organic solvents, allowing the tissue to become anhydrous and proceed to clearing. Water cannot serve as a dehydrating agent since it would keep the tissue hydrated and hinder subsequent steps. Formalin is a fixative used to preserve structure, not to remove water, and saline is a washing solution that maintains osmotic balance but doesn’t dehydrate.
