WebbFor example, the Ka constant for acetic acid (CH 3 COOH) is 0.0000158 (= 10 -4.8 ), but the pKa constant is 4.8, which is a simpler expression. In addition, the smaller the pKa value, the stronger the acid. For example, the pKa value of lactic acid is about 3.8, so that means lactic acid is a stronger acid than acetic acid. WebbTo calculate the ph of this buffer solution. After we have added 5.82 mL of 0.125 molar sodium hydroxide. We still should have a buffer solution because we are not adding enough sodium hydroxide to completely consume all of the acetic acid that is present the volume and concentration does not give us enough moles to react with all of these cD acid.

Any aqueous acid with a pKa value of less than 0 is almost completely deprotonated and is considered a strong acid.
