The pKa value for sodium octanesulfonate is typically around 2.0 to 2.5.
The conjugate acid is Hydrogen (H2), the pKa of which is 35.
From this salt the benzoate ion C6H5-COO- is a base ( the other part Na+ is neutral).This base has a pKB value of 9.80 (benzoate)The pKacid value of its conjugated benzoic acid ( C6H5-COOH) however ispKbenzoic-acid = 4.20 = pKa(which is (not surprisingly) equal to 14.0-pKbase = 14.0-9.80)
The effective pH range for a sodium phosphate buffer with a pKa value of 2.15 is typically 1.15 to 3.15. This range is optimal for buffering capacity at pH levels around the pKa value, ensuring stability and effectiveness for biological or chemical processes requiring a specific pH environment. Beyond this range, the buffer may not efficiently maintain the desired pH.
Sodium hydroxide is a strong base and does not have a pKa value. Instead, it dissociates completely in water to form hydroxide ions (OH-) and sodium ions (Na+).
The pKa value of Doxofylline is approximately 4.22.
The pKa value of pyridine is 5.2.
The pKa value of Acebrophylline is approximately 1.8.
The pKa value of azithromycin is around 8.4.
The pKa value of H2O is approximately 15.7.
The pKa value of acetylacetone is approximately 8.9.
The pKa value of benzylamine is approximately 10.4.
The pKa value of protonated pyrrole is approximately 0.8.
The pKa value of sodium borohydride is approximately 13.
The pKa value of benzoic acid is approximately 4.2.
The pKa value of oxybutynin chloride is around 8.0.
The pKa value of H3O is approximately -1.74. A lower pKa value indicates a stronger acid. In a solution, a lower pKa value for H3O means it is a stronger acid, leading to a more acidic solution.
