Carboxylic acids dissociate in an aqueous solution to generate a carboxylate anion and a proton. This makes them acidic in nature. The negative base to 10 logarithm of the acid dissociation constant Kₐ of the dissociation process is called pKₐ value. pKₐ expresses the acidity of the carboxylic acid. barbara lebek kleding

"WebCarboxylic acids are considered relatively weak acids with typical pKa values between 4 and 6. For instance, acetic acid (the one that you find in table vinegar) has pKa=4.75 while a sulfuric acid (your typical strong acid) has pKa=-3. So, your typical strong acid is over ten million times more acidic than a typical carboxylic acid. " - Cooh strong acid
