An unknown weak acid with a concentration of 0.32 M was found to have a pH of 2.7. Using the table of dissociation constants (Ka) below, determine what the likely identity of the acid is. Explain how you got your answer (hint - calculate the Ka in the same way you did for acetic acid in lab)
chemical
Ka
Formic acid
1.77 x 10-4
Propionic acid
1.35 x 10-5
Hydrocyanic acid
6.17 x 10-10
Hydrogen peroxide
2.00 x 10-12
