Trifluoroacetic acid pka

Answer: You need to specify a concentration of TFA. I will use 0.1M The pKa of TFA is 0.25 ( other values up to 0.5 are quoted, depending on the source) Ka = 10^-0.25 = 0.562 Calculate [H+] using Ka equation - unfortunately you have to use the full quadratic route because Ka is so high Let [....

Fluoroacetic acid is a organofluorine compound with formula CH 2 FCO 2 H. ... difluoroacetic acid and trifluoroacetic acid are far less toxic. Its pKa is 2.66, in contrast to 1.24 and 0.23 for the respective di- and trifluorinated acids. Uses.

A polypeptide thin film obtained by spontaneous polymerization of a film comprising an amphiphilic amino acid derivative monomer represent by formula (I): ##STR15## wherein R represents an organic group; XR 1 is an elimination group whose conjugated acid has a pka of not higher than 14; X represents --O--, --S--, or --N(R 2)--; R 1 represents.
