Plaster of Paris has the chemical nature of __________________?
Show answer Hide answer
Answer: C. Both A. and B.
Explanation
Plaster of Paris has the chemical formula CaSO4 point five water and is widely used for setting broken bones. Both the chemical composition statement and the medical application statement are completely correct and accurate. When mixed with water, it rehydrates and hardens rapidly into a solid gypsum structure. Plaster of Paris is produced by heating gypsum to drive off three-quarters of its chemically bound water. Orthopedic casts utilize this setting expansion property to create snug, supportive immobilization for fractures. The setting reaction is exothermic, releasing mild heat as the hemihydrate converts back into dihydrate gypsum.
Option A is correct regarding formula, but it misses the crucial medical application included in option C. Option B is correct regarding bone setting, but it lacks the chemical formula provided in option A. Plaster of Paris differs chemically and structurally from natural raw gypsum because of partial dehydration.
