Superphosphate is the mixture of

Options

A. Calcium phosphate and dil. `H_(2)SO_(4)`
B. sodium phosphate and dil. `H_(2)SO_(4)`
C. Potassium phosphate and dil. `H_(2)SO_(4)`
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding Superphosphate**: Superphosphate is a type of fertilizer that is primarily used to provide phosphorus to plants. It is produced by treating rock phosphate with sulfuric acid.

2. **Components of Superphosphate**: The main components of superphosphate are:
- Rock Phosphate (which is primarily calcium phosphate)
- Dilute Sulfuric Acid (H2SO4)

3. **Chemical Reaction**: When rock phosphate reacts with dilute sulfuric acid, it produces:
- Calcium Sulfate (gypsum)
- Phosphoric Acid (H3PO4)

4. **Types of Superphosphate**: There are two main types of superphosphate:
- Single Superphosphate (SSP): Contains about 16-20% phosphorus (P2O5).
- Triple Superphosphate (TSP): Contains a higher concentration of phosphorus (about 44-48% P2O5).

5. **Conclusion**: Therefore, superphosphate is a mixture of calcium phosphate and sulfuric acid, resulting in a product that is rich in phosphorus and beneficial for plant growth.

**Final Answer**: Superphosphate is a mixture of calcium phosphate and dilute sulfuric acid.
