It refers to the acidity of the fatty acid (which make up the oils). Every fatty acid is composed of a non-polar long chain of hydrocarbons (carbon and hydrogen) and a polar head made up of Carboxylic ACID. Every acid has something called pKa which determines the acidity of that acid.
The bigger the pKa (e.g. 25), the weaker the acid.
The smaller ther pKa (e.g. 2), the stronger the acid.
pKa is a measure of the strength of an acid in a solution. It is the negative logarithm of the acid dissociation constant (Ka), a value that indicates how readily an acid donates a proton in a chemical reaction. A lower pKa value signifies a stronger acid.
pKa is the acid dissociation constant for any acid. It is a measure of strength of the acid.
Ka is the equilibrium constant for an acid reaction. pKa is the -log of Ka
Just like you take -log of concentration of H to get pH, you take -log of Ka to get pKa

What is the pKa of drotaverine?
The pKa of drotaverine is around 8.67.
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.
What is the Pka value of Azithromycin?
The pKa value of azithromycin is around 8.4.
The Ka of an unknown weak acid is 5.4 x 10 to the power of negative 10. Determine the pKa of the weak acid?
pKa = -log KapKa = -log 5.4x10^-10pKa = 9.27
What is pKa valu of MeOH?
The pKa value of methanol (MeOH) is approximately 15.5. This means that methanol is a weak acid and will partially dissociate in water to form methoxide ion and a proton.
Where can you find a list of pka values?
You can find a list of pKa values in chemical databases, textbooks, or online resources such as the CRC Handbook of Chemistry and Physics, PubChem, or ChemSpider. These resources provide information on the acidity or basicity of molecules by listing their corresponding pKa values.
What is the pka of diisopropylamine?
The pKa of diisopropylamine is around 10-11.
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 drotaverine?
The pKa of drotaverine is around 8.67.
What is the pKa of Triethylamine?
The pKa of Triethylamine is approximately 10.75.
What is the pKa of ethanol?
The pKa of ethanol is approximately 16.
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.
