The conjugate acid is Hydrogen (H2), the pKa of which is 35.
The pKa value for sodium octanesulfonate is typically around 2.0 to 2.5.
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.
Sodium Hydride is a strong base/alkali. It is an inorganic salt comprising of positively charged sodium ions, and negatively charged hydride (hydrogen) ions: Na+H-. It is a good source of the uncommon hydride ion. (NB Sodium hydride, NaH, is different to Sodium HYDROXIDE, NaOH, which is common table salt.)
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 sodium borohydride is approximately 13.
The pKa value for sodium octanesulfonate is typically around 2.0 to 2.5.
The pKa value of ceftriaxone is approximately 3.8.
sodium hydride
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.
Sodium Hydride is a strong base/alkali. It is an inorganic salt comprising of positively charged sodium ions, and negatively charged hydride (hydrogen) ions: Na+H-.

Sodium hydride is an ionic compound.
The pKa value of Doxofylline is approximately 4.22.
When hydrogen reacts with sodium, it forms hydrogen gas and sodium hydride. The chemical equation for this reaction is 2Na + 2H2 -> 2NaH. Sodium hydride is a white solid that is highly reactive with water.
