WebJan 16, 2024 · The resulting determinations of phosphorus were as follows: By method (1), 1.622 and 1.625 per cent.; by (2), 1.626 and 1.631 per cent.; average of all, 1.626 per … WebThe current application is a titrimetric adaptation of a classical gravimetric procedure. Here titration of phosphate ions with a magnesium nitrate, Mg(NO 3) 2 solution produces an insoluble precipitate of MgNH 4 PO 4 at alkaline pH. The formation of insoluble MgNH 4 PO 4 is a strong exothermic reaction that is monitored by thermometric titration.
WebA new complexometric method for the determination of phosphorus in organic compounds is described. After combustion in an oxygen-flask, phosphorus is precipitated as cereus phosphate. The excess cereus ion is back-titrated at pit 6--7 with EDTA in the presence of methylthymol blue or xylenol orange indicators.
