When phosphate rock is treated with phosphoric acid, a __________ superphosphate is produced.

When phosphate rock is treated with phosphoric acid, a single superphosphate is produced. This reaction involves the acid reacting with the calcium phosphate present in the rock, resulting in a soluble phosphate compound. The treatment increases the availability of phosphorus, which is an essential nutrient for plants, making the resulting superphosphate highly beneficial as a fertilizer in agriculture.

Furthermore, the process enhances the solubility of phosphate, improving its uptake by plants. In agricultural practices, this process is crucial for enhancing soil fertility, especially in phosphate-deficient soils. The single superphosphate (SSP) contains approximately 16-20% phosphorus pentoxide (P₂O₅) and also provides sulfur and calcium, vital for various biological processes in plants. Overall, SSP plays a significant role in ensuring sustainable agricultural practices by supplying necessary nutrients for crop growth.
