whereas triple superphosphate contains over 40 percent phosphorus The remaining phosphate fertiliser group is ammonium phosphate NH 4 H 2 PO 4 Phosphoric acid is an important industrial acid used in the manufacture of fertilisers for the corrosion treatment of metals and in the production or inorganic phosphates especially detergent and food grade
In reality the existence of 49 known calcium phosphates 14 magnesium phosphates 49 aluminum phosphates and 51 iron phosphates and some contain one or more of these cations points to the complexity of the chemistry of phosphate minerals in soils and it is dubious that any fertilizer reaction species or series is more than illustrative
A solution containing nitrates of silver iron Calcium is an alkaline earth metal so the precipitate seen in the last step of the analysis must be calcium phosphate Calcium forms 2 ions and phosphates are 3− ions so the formula must be Ca3 PO4 2 Sets found in the same folder CH121 Chapter 4 56 terms
