Results and discussion
- Dissociating properties:
- yes
Dissociation constant
- pKa:
- 18.48
- Temp.:
- 25 °C
Applicant's summary and conclusion
- Conclusions:
- The estimated pKa of the main components is 18.48
- Executive summary:
A SPARC estimation of the pKa of the main components gives a pKa of 18.48. This pKa indicates that no significant dissociation occurs within the pH range 5 -9 thus no further testing is necessary.
