0·5 N sodium hydroxide solution (free from carbon dioxide) shall be added, the volume added being such that it contains an excess
sodium hydroxide beyond that necessary to dissolve the precipitate. The stopper or bung shall be replaced, and the flask shaken until the precipitate is completely dissolved. The excessof sodium hydroxide shall be titrated with 0·5 N hydrochloric acid solution, about 0·5 to 1 millilitre
reagent (c) being added and the end point being taken as the sharp change from green-blue to yellow. The volume
0·5 N hydrochloric acid used shall be deducted from the volume
0·5 N sodium hydroxide, previously added, in order to ascertain the volume
0·5 N sodium hydroxide equivalent to the phosphorus. 1 millilitre 0·5 N sodium hydroxide solution is equivalent to 0·596 milligrams
phosphorus. A " blank " determination shall be carried out on all the reagents, omitting only the sample, and using 0·1 N solutions
acid and alkali for the titration. The " blank " shall be calculated in terms
0·5 N sodium hydroxide and the result first obtained corrected accordingly. Total phosphorus in all substances except basic slag. (
