Question: The silkworm spins a cocoon after…? (IFFCO 2022)
Options:
H2PO4-
HPO42-
PO43-
H3PO4
✅Explanation:
In alkaline soils (high pH), phosphorus tends to react with calcium and magnesium, forming less soluble compounds. H3PO4 (phosphoric acid) is the most acidic form of phosphorus. In alkaline conditions, it readily reacts with calcium and magnesium, becoming much less available for plant uptake.
