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 for Hydroastatic acid and Periodic acid?
There are no accurate pKa value of these two, extremely STRONG acids, any value of >> 1000 (up to >> 1.0*10+9) will do.
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 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 picricacid formual?
picric acid (or 2,4,6-trinitrophenol) is more acidic than benzoic acid The pKa or picric acid is 0.3 and that of benzoic acid is 4.2
What is the pka value of ether?
The pka of a protonated ether (the conjugate acid) is about -3.5
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 Hydroastatic acid and Periodic acid?
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 gross calorific value of benzoic acid?
007
Is there a pKa value for CO2 plus H2O - H2CO3?
pKa = 6.36 of carbonic acid to HCO3-
Is sodium benzoate soluble in sodium chloride?
Yes, Benzoic acid is a weak acid (pKa ~ 4.2) that will dissolve in weak base such as sodium bicarbonate (pKa ~ 6.4)
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.

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 for sodium octanesulfonate?
The pKa of sulfonic acid is < 0
Which is more acidic formic acid or benzoic acid?
Benzoic Acid
