Which is more acetic water or acetylene?
Do you mean acidic? Water has a pKa of ~14 and acetylene has a pKa of ~25, so water is more acidic.
What is the pka of cyclohexane?
pKa is measured for acid in aqueous solution while hexane is an organic liquid immiscible with water so pKa value is meaning less for hexane.
Why does a hydrophobic environment increase the pKa of Histidine?
The pKa, or acid dissociation constant, of an amino acid is strongly tied to the properties of the surrounding solvent. The hydrophobic core of a protein is a distinctly different environment than the water exposed surface of the protein and the pKa in the core is different than the normal, solvent exposed pKa. This is related to the dielectric constant, or the ease at which charge is "felt" over a distance, which is much lower in the hydrophobic core of the protein. In addition, the now fixed locations of other possibly charged amino acids nearby will also impact the pKa of the residue.
What is the pka of diisopropylamine?
pKa=40

Does pka changes with temperature?
pKa (dissociation constant) is variable with temperature.

Is 1-butanol basic in water?
pka=9.9 therefore, it is basic in water.

What is the pka value for NaCN?
NaCN doesn't really have a pKa. In water it becomes Na^+ and CN^-. The CN^- is a base so it will have a Kb and pKb. If you want the pKa of the conjugate acid (HCN), you can find that from 1x10^-14/Kb.
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.
How do you determine the pKa value of an organic compound for HPLC method?
the organic compound three kind normal, acid and basic compound for acid compound the pKa from 3 to 5, normal pKa around 7 and basic compound more than 7 also you can know the kind of organic compound from structure that you can see acidic or basic grope like carboxylic acid or amine.
What is the PH value of potassium sulphate?
The pKa of HSO4- (the second pKa of H2SO4) is 1.92. The Ka is thus 0.0120

pKa=40

What is the pKa of cholic acid and urea?
Cholic acid is a bile acid, a white crystalline substance insoluble in water, with a pKa of about 5.5. Urea is an organic compound with the chemical formula (NH2)2CO often found in the urine of animals, with a pKa of about 0.18.
