Hach molybdenum method

WebBrief Method Summary. Ammonium molybdate and antimony potassium tartrate react in an acid medium (potassium pyrosulfate) with dilute solutions of phosphorus to form a yellow colored antimony-phospho-molybdate complex. This complex is reduced to an intensely blue-colored (molybdenum blue) complex by ascorbic acid. WebPhosphorus (P) is a chemical element with an atomic number of 15 and an atomic mass of 31. Due to its high reactivity, phosphorus does not naturally exist as a free element. Phosphorus generally occurs as phosphate in minerals. Phosphate is typically found in the Earth’s crust at a concentration of about 1 gram per kilogram.
