1. Method: Mix a solution of calcium chloride (CaCl2) with a solution of sodium sulphate (Na2SO4) and allow the reaction to occur. Filter and wash the resulting precipitate to obtain calcium sulphate (CaSO4).
2. Balance equation:
CaCl2 + Na2SO4 → CaSO4 + 2NaCl
3. Net ionic equation:
Ca2+ + SO42- → CaSO4(s)
4. Observations: Initially, mixing the solutions will result in no visible change. However, after a few minutes, a white precipitate will start to form. This precipitate will continue to grow until the reaction is complete. Filtration and washing of the precipitate will result in a white solid which is calcium sulphate.
5. Properties of calcium sulphate that make it suitable for use in plaster:
- Calcium sulphate has good binding properties which make it effective in holding together particles of other materials in a solid mass.
- It has a moderately high compressive strength which allows it to withstand weight and pressure without breaking.
- It is fire-resistant and non-toxic, making it safe for use in construction and medical applications.
- It is easy to work with and can be shaped and molded into different forms to suit a variety of needs.

1. Method: Mix a solution of barium chloride (BaCl2) with a solution of sodium sulphate (Na2SO4) and allow the reaction to occur. Filter and wash the resulting precipitate to obtain barium sulphate (BaSO4).
2. Balance equation:
BaCl2 + Na2SO4 → BaSO4 + 2NaCl
3. Net ionic equation:
Ba2+ + SO42- → BaSO4(s)
4. Observations: Initially, mixing the solutions will result in no visible change. However, after a few minutes, a white precipitate will start to form. This precipitate will continue to grow until the reaction is complete. Filtration and washing of the precipitate will result in a white solid which is barium sulphate.
5. Properties of barium sulfate that make it suitable for use in x-ray photography:
- Barium sulphate is radiopaque, meaning it blocks x-rays from passing through it, making it useful as a contrast agent in certain types of x-ray imaging.
- It is inert and non-toxic, making it safe to ingest in small amounts as a contrast agent for gastrointestinal tract imaging.
- It has a high melting point and is stable at high temperatures, making it useful in high-temperature applications such as ceramic manufacturing.
