Summary
-
1.
We have shown the possibility of reciprocal volumetric determination of cerium salts and trisodium phosphate. The end of the titration is fixed by phenolphthalein or potentiometrically.
-
2.
The relative accuracy of the determination of cerium salts and Na3PO4 in solutions which contain 0.01–0.10 g-ion/liter of cerium or mole/liter Na3PO4 varies in the range±0.3–3.8% The time of the determination is 30–60 minutes.
