pKaView Icon pKaViewTM   Database of Over 1000 pKa Values

pKaView is designed to be a convenient user interface for viewing the pKa values of over 1000 compounds. The database contains the names of the compounds in addition to the chemical structure ("Compound Structure"). Also included is the chemical structures of the conjugate acids and bases that represent the most highly protonated species ("Conjugate Acid") and the most unprotonated species ("Conjugate Base") of a series.

There is also a searching function that allows you to search the chemical names to create a list ("Find List") of compounds to browse.

It is also possible to add your own materials and their pKa values and the three chemical structures that are typical for each entry. Below is a screen shot of the program.
