Triple phosphate

First, find the mass of H2S04 that reacted, then determine the mass of superphosphate (triple phosphate). 

Most elemental ph osphorus is used to manufacture phosphoric acid, a solid that is used to produce triple-phosphate fertilizers. Some soils require large amounts of phosphorus to produce a viable crop. 

Ca3(P04)2 + 4H3PO4 3Ca(H2P04)o This product is much richer in phosphorus than the superphosphate it is called triple phosphate. Over ten million tons of phosphate rock is converted into phosphate fertilizer each year. 

Calculate the amount of phosphorus (as percent of P2O5) in superphos-phate of lime and in triple phosphate. ... 

Struvite stones (also called triple phosphate or infection stones) are composed of magnesium ammonium phosphate hexahydrate. The formation of such stones requires urinary tract infection with urea splitting organisms and such stones are therefore more common in females and in certain patient populations (e.g, paraplegics), The risk of progression to CKD appears higher in patients who develop infection stones than in other forms of stone disease. 

Superphosphate, a water-soluble fertilizer, is sometimes marketed as triple phosphate. It is a mixture of Ca(H2P04)2 and CaS04 on a 1 2 mole basis. It is formed by the reaction... 

Ammonio-Magfnesian Phosphate—Triple phosphate—Mg(NH,) P04-[-6 Aq—137-(-108—is produced when an alkaline phosphate and jSTH (HO are added to a solution containing Mg. When heated it is converted into mag nesium p3rrophosphate MgjPj07, in which form H3PO and Mg are usually weighed in quantitative analysis. 

The administration of a high-phosphate diet to castrated male sheep produced phosphatic calculosis. Triple phosphate crystals appear in the urine as early as 24 hours after the diet is instituted. Precipitation occurs when the urine pH reaches values of 8.2-8.5. The concentrations of magnesium, ammonium, and Pi and the overall ionic strength modulate the precipitation. The triple phosphate crystals are agglomerated to form small, round bodies 3-7 p in diameter called microcalculi. Later, microcalculi are packed together into an organic envelope. 

This product is called triple phosphate and contains 48% of assimilable P2O5. 

In addition to triple phosphate and ammonia itself, another major fertilizer is ammonium sulfate. Speculate on how this might be efficiently produced. 

Phosphates and carbonates of Ca and Mg (white, amorphous deposit). Ammonium magnesium phosphate (triple phosphate) in aimnoniacal urine. (Large, prismatic crystals.) Colourless.
