P₂O₅ content in triple superphosphate is about __________ percent.

ANS:A - 42-50

Triple superphosphate (TSP) is a widely used phosphorus fertilizer. Its composition is primarily phosphorus pentoxide (P2O5), which is derived from phosphate rock. The P2O5 content in TSP usually falls within the range of 42-50%. This means that for every 100 parts of TSP, approximately 42-50 parts are phosphorus pentoxide. This concentration of phosphorus pentoxide makes TSP an effective source of phosphorus for plants, providing essential nutrients to support their growth and development. The variability in the P2O5 content can depend on factors such as the source of phosphate rock and the manufacturing process.
