- Conclusions:
- The water solubulity of phosphorous as element is 1.98 x 10^-4 and zinc as element is 2.20 x 10^-3.
The water solubility of phosphorous as equivalent test item is 2.49 x 10^-3 and of zinc as equivalent test item is 3.27 x 10^-3. - Executive summary:
Using the flask method, designed to be compatible with Method A.6 Water Solubility of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 105 of the OECD Guidelines for Testing of Chemicals, 27 July 1995, the water solubility at 20.0 ± 0.5 °C is shown in the following table:
Element Concentration (g/L) as Element Concentration (g/L) as equivalent test item Phosphorous 1.98x10^-4 2.49x10^-3 Zinc 2.20x10^-3 3.27x10^-3
Reference
| Element | Concentration (g/L) as Element | Concentration (g/L) as equivalent test item |
| Phosphorous | 1.98x10^-4 | 2.49x10^-3 |
| Zinc | 2.20x10^-3 | 3.27x10^-3 |
