Question

Given below are two statements:
Statement I: Single superphosphate, double superphosphate, and triple superphosphate are monocalcium phosphates.
Statement II: Monocalcium phosphates are water-soluble and thus have high leaching losses.
In light of the above statements, choose the most appropriate answer from the options given below:

• A. Both Statement I and Statement II are true
• B. Both Statement I and Statement II are false
• C. Statement I is correct but Statement II is false
• D. Statement I is incorrect but Statement II is true

Hint:

Phosphate fertilizers:
- SSP, DSP, TSP: Contain monocalcium phosphate.
- Water-soluble P: Prone to leaching.
- P fixation in soil reduces availability.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
This question tests knowledge of phosphate fertilizers.

Step 2: Detailed Explanation:
Single superphosphate (SSP), double superphosphate (DSP), and triple superphosphate (TSP) contain monocalcium phosphate [Ca(H₂PO₄)₂].
This statement is true.
Monocalcium phosphate is water-soluble and can be leached from the soil.
Thus, both statements are true.

Step 3: Final Answer:
Thus, both statements are true, which corresponds to option (A).
