What is the pKa value for Hydroastatic acid and Periodic acid?
Rstar360
There are no accurate pKa value of these two, extremely STRONG acids, any value of >> 1000 (up to >> 1.0*10+9) will do.

What is the pka value of ether?
The pka of a protonated ether (the conjugate acid) is about -3.5
What is the pKa value of benzoic acid?
4.2
Is there a pKa value for CO2 plus H2O - H2CO3?
pKa = 6.36 of carbonic acid to HCO3-
PKa of NaHCO3?
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.
Why sodium hydrogensulphate functions as an acid and look up its pKa value?
Sodium hydrogensulfate contains the HSO4- ion therfore it can function as an acid. It's pKa value is 1.9.

What is the pKa value of benzoic acid?
4.2
What is pka value for sodium hydride?
The conjugate acid is Hydrogen (H2), the pKa of which is 35.

What is the pKa value for sodium octanesulfonate?
The pKa of sulfonic acid is < 0
What is pka value for sodium bicarbonate?
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.
What is pKa value of aminoacids?
The pKa values of Amino acids depends on its side chain. However, the protonated amine group (NH3+) tends to have a pKa greater than 8.8, whereas the carboxylic acid (COOH) tends to have a pKa of 1.8 - 2.8. If you keep your amino acid at a pH between this value, you will likely have a Zwitter ion.
What is definition of pka value and difference between pH and pKa?
A pKa value is a measurement used for bases and acids. The measurement pH applies to hydronium ion concentrations that are in a solution, whereas pKa only applies to determining the amount of dissociation an acid wants to do in a solution.
What is the pka of sodium benzoate?
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)
What is the pka of bromoacetic acid?
pKa=2.86
