Urea phosphate is an organic compound of carbon , hydrogen , nitrogen , oxygen and phosphorus . Its formula is CO NH sub 2 sub sub 2 sub .H sub 3 sub PO sub 4 sub . It is made by reacting urea with phosphoric acid . It is sometimes used as a fertilizer as such, its NPK formula is 17 44 0. It is soluble in water, and produces a strongly acidic solution. Urea phosphate is sometimes added to blends which contain calcium nitrate and magnesium nitrate to produce water soluble formulas such as 15 5 15, 13 2 20, and 13 2 13. The acidity of urea phosphate allows calcium Ca , magnesium Mg and phosphorus P to co exist in solution. Under less acidic conditions, there would be precipitation of Ca Mg phosphate s.

Orphan date August 2008 refimprove date August 2008 This is applicable to laboratory analysis particularly in the determination of water pollution . Such an analytical test may be either qualitative or quantitative. A Quantitative method to determine the amount of phosphate present in samples such as boiler feedwater is as follows. A measured amount of boiler water is poured into a mixing tube and ammonium heptamolybdate reagent is added. The tube is then stoppered and vigorously shaken. The next step is to add dilute stannous chloride reagent, which has been freshly prepared from concentrated stannous chloride reagent and distilled water, to the mixture in the tube. This will produce a blue color due to the formation of molybdenum blue and the depth of the blue color indicates the amount of phosphate in the boiler water. The absorbance of the blue solution can be measured with a colorimeter and the concentration of phosphate in the original solution can be calculated. Alternatively, a direct but approximate reading of phosphate concentration can be obtained by using a Lovibond comparator . This method for phosphate determination is known as Deniges method ref http www3.interscience.wiley.com journal 112603635 abstract?CRETRY 1&SRETRY 0 ref . A simple Qualitative method to determine the presence of phosphate ions in a sample is as follows.
