Is ammonia acid?
Ammonia (NH3) is a weak base that is in equilibrium with ammonium (NH4+) in aqueous solution. pKa value of NH3=9.25.
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 the pKa of HCHO2?
The pKa of: NH4(+) = 9.4 NH3 = 38 NH2(-) = EXTREMELY HIGH (due to the the instability of compounds like NH(2-) and N(3-) the pKa values are not currently known -- they really aren't around for long enough to get an accurate pka value. There may be experimental values in the literature somewhere, but they are likely not going to be the same from source to source!)
HCLO and HCL what more acidic?
HClO pKa = 7.497 HCl pKa = -8.000HCl is a far stronger acid.For future reference: type the name of the compound into wikipedia and look down the right hand side to find it's pKa value. Do the same for your second compound.The lowest pKa is the more acidic compound.
What is the pka of diisopropylamine?
pKa=40
Which side will the reaction go NH3 H2O NH4 OH- using pka's of the acid and Strong acid and base?

pKa = 15
PKa value of diethylmalonate?
It is around pKa=13
What is the pka value of Doxofylline?
Doxofylline Pka value is about 9.8.
Does pka changes with temperature?
pKa (dissociation constant) is variable with temperature.
