The pKa of sulfonic acid is < 0
The conjugate acid is Hydrogen (H2), the pKa of which is 35.
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 for HCO3- ----> CO3-2 + H+ is 10.33 I assume you would have a reaction such as K+ HCO3- + H2O ------> K+CO3-2 + H3O+ In which the potassium acts as a neutral ion.
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.
The pKa value of sodium borohydride is approximately 13.
The pKa value of ceftriaxone is approximately 3.8.
The conjugate acid is Hydrogen (H2), the pKa of which is 35.
Sodium hydrogensulfate contains the HSO4- ion therfore it can function as an acid. It's pKa value is 1.9.
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+).
There are two answers: bicarbonate has two pKa's - because bicarbonate can gain a proton to become carbonic acid or lose a proton to become carbonate. Two reactions; two pKa's. The pKa for bicarbonate carbonic acid reaction is 6.4 The pKa for bicarbonate carbonate reaction is 10.3 Both pKa's are temperature sensitive.
The pKa for HCO3- ----> CO3-2 + H+ is 10.33 I assume you would have a reaction such as K+ HCO3- + H2O ------> K+CO3-2 + H3O+ In which the potassium acts as a neutral ion.
The pKa value of Doxofylline is approximately 4.22.
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 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.
