Explanation:
Gypsum and plaster of Paris are two different forms of calcium sulfate with different properties and uses. Here is a detailed explanation of each statement:
Gypsum:
- Gypsum is a naturally occurring mineral composed of calcium sulfate dihydrate (CaSO4·2H2O).
- It is a soft, white or gray mineral that can be found in sedimentary rock formations.
- Gypsum is widely used in construction, agriculture, and industry due to its properties such as fire resistance, sound insulation, and soil conditioning.
- Gypsum is not suitable for casting or molding due to its low setting time and low strength.
Plaster of Paris:
- Plaster of Paris is a form of gypsum that is obtained by heating gypsum at a high temperature to remove its water content.
- The resulting powder can be used for casting, molding, and sculpting due to its ability to harden quickly when mixed with water and its high strength.
- Plaster of Paris is widely used in the medical field for making casts and splints, as well as in art and crafts for creating sculptures and decorations.
Correct Statement:
- Gypsum contains a lower percentage of calcium than plaster of Paris.
- This statement is true because plaster of Paris is a form of gypsum that has been heated to remove its water content, resulting in a higher concentration of calcium sulfate.
- Plaster of Paris typically contains 70-75% calcium sulfate, while gypsum contains only about 50% calcium sulfate.
- This difference in calcium content affects the physical properties and uses of each material, as discussed above.
Conclusion:
In conclusion, the correct statement is that gypsum contains a lower percentage of calcium than plaster of Paris. Understanding the properties and uses of each material can help in selecting the appropriate material for a specific application.

Gypsum is CaSO4.2H2O
while Ploster of peris is 2CaSO4.H2O
thus Ploster of peris contain greater percentage than gypsum.
while Ploster of peris is 2CaSO4.H2O
thus Ploster of peris contain greater percentage than gypsum.
