The pKa value for sodium bicarbonate (NaHCO3) is 10.3. This provides a measure of the acid strength of bicarbonate.
People often make the mistake of reporting the pKa value of 6.3 for bicarbonate. However, that is the pKa value of carbonic acid (not bicarbonate). It relates to the ease of the first deprotonation of carbonic acid to form bicarbonate. The pKa of bicarbonate relates to the deportation of bicarbonate to form carbonate. This distinction is important, since carbonic acid has two pKa's, the higher of which represents that second deprotonation.
The pKa of NaHCO3 (sodium bicarbonate) is approximately 6.4. This means that at pH values below 6.4, bicarbonate ions will tend to pick up a proton and act as a weak acid, while at pH values above 6.4, bicarbonate ions will tend to lose a proton and act as a weak base.

What is the pka of bromoacetic acid?
The pKa of bromoacetic acid is approximately 2.64.
What is the pka value of Doxofylline?
The pKa value of Doxofylline is approximately 4.22.
What is the pKa of Triethylamine?
The pKa of Triethylamine is approximately 10.75.
How do you calculate pka?
To calculate pKa, you can use the Henderson-Hasselbalch equation: pKa = pH + log([A−]/[HA]), where [A−] is the concentration of the conjugate base and [HA] is the concentration of the acid. Alternatively, you can look up the pKa value in a table or use a chemical database.

How do you calculate pka?
To calculate pKa, you can use the Henderson-Hasselbalch equation: pKa = pH + log([A−]/[HA]), where [A−] is the concentration of the conjugate base and [HA] is the concentration of the acid. Alternatively, you can look up the pKa value in a table or use a chemical database.
How can you calculate pka valve if pH is given?
You can calculate the pKa value by using the Henderson-Hasselbalch equation: pH = pKa + log([A-]/[HA]), where [A-] is the concentration of the conjugate base and [HA] is the concentration of the acid. Rearranging the equation, you can solve for pKa by taking the antilog of both sides after isolating pKa.
Does pka changes with temperature?
pKa (dissociation constant) is variable with temperature.
