Applicant's summary and conclusion

Conclusions:
The measured pH of the diluted NC2000S salt solutions (highest pH 6.63 and lowest pH 6.49) shows that the salt is an almost neutral salt at salt concentrations between 0.1 and 0.3 molar.
Executive summary:

The pH of NC2000S salt (concentration of 0.10, 0.15 and 0.30 molar added to water pH 7) were measured with  Knick pH meter 763, multimeter-calimatic.

The measured pH of the diluted NC2000S salt solutions (highest pH 6.63 and lowest pH 6.49) shows that the salt is an almost neutral salt at salt concentrations between 0.1 and 0.3 molar.
