iodine; sodium hydrogencarbonate in water
hydrolysis of PCl3 at 0°C and pH 5.7 (acetate-buffered) and oxi- dation of the obtained soln. with iodine in NaHCO3-soln. leads to hypo- phosphoric acid;; isolation in form of the Ag-salt in 10percent yield;;

copper(II) nitrate in not given
byproducts: Cu, Cu-phosphide; addition of white P into a warm Cu(NO3)2-soln. yields in formation of nitrous gases, H3PO3, H3PO4 and H4P2O6 and in pptn. of Cu and Cu-phos- pide; mechanism given;;
