__________ is used by doctors to set fractured bones.

Correct option is C

The correct answer is (C) CaSO₄ · 1/2 H₂O

Explanation:

The compound used by doctors to set fractured bones is Calcium Sulfate Hemihydrate (CaSO₄ · 1/2 H₂O), commonly known as Plaster of Paris. It is used in the form of a paste, which hardens upon setting, making it ideal for immobilizing fractures during healing.

Information Booster:

• Plaster of Paris (CaSO₄ · 1/2 H₂O) is created by heating gypsum (CaSO₄ · 2H₂O) to a high temperature.

• When mixed with water, it forms a paste that hardens and sets, making it useful in orthopedics.

• It has a quick-setting property, making it perfect for use in medical applications like setting fractures.

• It is commonly used in the form of casts for broken bones.

• Plaster of Paris is used for creating molds in the medical field, as well as in the construction and art industries.

Additional Information:

• ZnSO₄ · 10H₂O and ZnSO₄ · 7H₂O : Zinc sulfate is not used for setting bones, although it has applications in medicine and as a supplement.

• CuSO₄ · 5H₂O : Copper sulfate is mainly used as a fungicide and for other industrial applications but is not used in setting fractures.
