Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1886 edition. Excerpt: ...a pure light lemon colour; this is uranic phosphate 2(Ur2O3), P2O3, the percentage composition of which is 80-09 of uranic oxide, and 19'91 of phosphoric acid. The two precipitates are accurately weighed, and should agree to within a trifle. If they differ, the mean is taken to represent the amount of P2O5 in the given quantity of tricalcic phosphate, from which may be calculated the strength of the solution to be used as a standard. Of course any other accurate method of determining the P2O5 may be used in place of this. The actual standard required is 5 gm. of pure tricalcic phosphate per liter; and it should be adjusted to this strength by dilution, after the actual strength has been found. In this way is obtained a standard which agrees exactly with the analysis of a superphosphate or other similar manure. Standard Uranium Solution, ---This is best adjusted to such strength that 25 c.c. are required to give the faint chocolate colour with ferrocyanide, when 50 c.c. of the standard acetic solution of calcic phosphate are taken for titration. Working in this manner each c.c. of uranium solution represents 1 per cent. of soluble tricalcic phosphate, when 1 gm. of manure is taken for analysis, because 50 c.c. of the calcic phosphate will contain monocalcic phosphate equal to 0-25 gm. of Ca: lP2Os and will require 25 c.c. of uranium solution to balance it. These standards are given as convenient for manures, but they may be modified to suit any particular purpose. The Analysis in case of Superphosphate free from Fe and At, except in mere traces: --10 gm. of the substance is weighed, placed in a small glass mortar and gently broken down by the pestle, cold water being used to bring it to a smooth cream. The material should not be ground or...show more
