- yes
- No.:
- #1
- pKa:
- 0.7
- Temp.:
- 20 °C
- Remarks on result:
- other: Strongest pKa(Acid): 0.70 +/- 0.50
- Conclusions:
- A dissociation constant value of 0.7 was obtained using an accepted calculation method. The result is considered to be reliable
- Executive summary:
- A dissociation constant value of 0.7 was obtained using an accepted calculation method. The result is considered to be reliable
Reference
An estimated pKa of 0.7 indicates that this acid is fully dissociated in the environmental pH range 4 to 9.
