A 25.00-mL sample of propionic acid, HC3H5O2, of unknown concentration A 25.00-mL sample of propionic acid, HC3H5O2, of unknown concentration was titrated with 0.151 M KOH. The equivalence point was reached when was titrated with 0.151 M KOH. The equivalence point was reached when 41.28 mL of base had been added. What is the pH at the equivalence point? âââ41.28 mL of base had been added. What is the pH at the equivalence point? âââ Kaâââfor propionic acid is âââ1.3Ã10â5âââat 25°C.Kaâââfor propionic acid is âââ1.3Ã10â5âââat 25°C.
