What is the pKa of H2O2?

As André Macherius mentioned H2O2 dissociates forming HO2- and H+. The pKa is 11.75 according to Wikipedia. This is of some importance as the base form is more reactive e.g. in several of the hydrolysis reactions. For this reason commercial H2O2 solutions are usually added some acid (phosphoric) to increase the stability.

What are the pKa values?

pKa Data Compiled by R. Williams page-1 pKa Values INDEX Inorganic 2 Phenazine 24 Phosphates 3 Pyridine 25 Carboxylic acids 4, 8 Pyrazine 26 Aliphatic 4, 8 Aromatic 7, 8 Quinoline 27 Phenols 9 Quinazoline 27 Alcohols and oxygen acids 10, 11 Quinoxaline 27 Amino Acids 12 Special Nitrogen Compounds 28 Peptides 13 Hydroxylamines 28

How many pKa's does sulfuric acid have?

If you look at a molecule like Sulfuric acid, H2SO4, a molecule with more than one acidic hydrogen, it's going to have two pKa's, one for each proton. In these cases, you can avoid confusion if you talk about the pKa of the proton instead of the pKa of the molecule.

Is the pKa of an acid dependent on the base?

The pKa of the acid isn't dependent on the pKb or strength of the base. The equilibrium constant, Keq, which roughly measures how how readily the reactants will become the products, will. Think of it like two children who want the same toy. Suzy has the toy. Billy wants to take it.
