WebDehydrating agent. A dehydrating agent is a substance that dries or removes water from a material. In chemical reactions where dehydration occurs, the reacting molecule loses a molecule of water. Sulfuric acid, concentrated phosphoric acid, hot aluminum oxide, and hot ceramic are common dehydrating agents in these types of chemical reactions. WebFat remains in the tissue following infiltration with: Carbowax. Methanol functions as a(n): Dehydrating agent only. The most effective method for rapidly freezing tissue is using: Liquid nitrogen/isopentane The amount of time a specimen needs to remain in decalcifying solution is NOT influenced by the: Processing schedule . When tissues have ...
