Question

f. In the manufacture of P fertilizers, Give the chemical reactions when the following fertilizers are manufactured a) Diammonium Phosphate (DAP) (2 Marks) b) Triple superphosphate (TSP) (4 Marks)

Answer 1

a) Diammonium Phosphate (DAP):The chemical reaction for the manufacture of Diammonium Phosphate (DAP) is as follows:2NH3 + H3PO4 → (NH4)2HPO4In this reaction, ammonia (NH3) reacts with phosphoric acid (H3PO4) to form Diammonium Phosphate (DAP), which is a commonly used nitrogen and phosphorus fertilizer.b) Triple superphosphate (TSP):The chemical reaction for the manufacture of Triple Superphosphate (TSP) is as follows:2H3PO4 + 3Ca(OH)2 → Ca3(PO4)2 + 6H2OIn this reaction, phosphoric acid (H3PO4) reacts with calcium hydroxide (Ca(OH)2) to form Calcium Phosphate (Ca3(PO4)2), which is the main component of Triple Superphosphate (TSP). TSP is a highly concentrated source of phosphorus and is commonly used in agriculture to provide essential nutrients to crops.
