Key result

Water solubility:

110 g/L

Conc. based on:

test mat.

Temp.:

20 °C

pH:

11

Remarks on result:

other: Mean value of 6 samples

Details on results:

The concentrations of the test item measured in at least the two last vessels do not differ by more than +/- 15 % and there is no trend in the values, thus the test is satisfactory.
The relative standard deviation (repeatability) of the concentrations in all six samples was smaller than 15 % and the three duplicate sets of samples showed no tendency of increasing concentration values. Thus the test was satisfactory.

No remarks

Conclusions:

In conclusion the water solubility of calcined Lithium hydroxide was determined to be 110 g/L at 20 +/- 0.5 °C using the flask method for the performance of the main test.

Executive summary:

The purpose of the study was to evaluate the solubility of calcined Lithium hydroxide in water at 20 ± 0.5 °C. In conclusion the water solubility of calcined Lithium hydroxide was determined to be 110 g/L at 20 +/- 0.5 °C using the flask method for the performance of the main test.
