Question

________ is used by doctors to set fractured bones?

• A. ZnSO4·10H2O
• B. ZnSO4·7H2O
• C. CaSO4·1/2H2O
• D. CuSO4·5H2O

Answer 1

Answer:

C. CaSO4·1/2H2O

Calcium Sulfate (CaSO₄·1/2H₂O) is commonly used by doctors to set fractured bones, as it helps in the formation of a hard cast. The white powder used by doctors to support fractured bones is typically calcium sulfate, commonly known as plaster of Paris. The chemical formula for this compound is CaSO₄·½H₂O. It is prepared by heating gypsum (CaSO₄·2H₂O) to about 150°C, which removes water and converts it to plaster of Paris
