50 mls. of the calcium nitrate solution are placed in a 120 g glass bottle fitted with a screw cap. To this solution is added that volume of solution (c) required to produce a concentration of 2-amino-phosphonoacetic acid monohydrate of 5 ppm, 7.5 ppm or 10 ppm, respectively, in the final volume (100 ml) of test solution (e.g. 1.0 ml of 0.1% of solution (c) produce a concentration of 10 ppm of 2-amino-phosphonoacetic acid monohydrate in the test solution). 50 ml of solution (b) are added and the mixture is shaken. The test solution is stored in a constant temperature bath, maintained at 25° C., for 24 hours.
