WebFor 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. WebA typical example of an Arrhenius acid is something like hydrochloric acid (HCl). While a typical example of an Arrhenius base is something like sodium hydroxide (NaOH). Once those species dissociate, HCl gives H + into the solution, while NaOH gives off the OH – ion. WebAug 23, 2016 · The approximate value of pKa is −7 for H Cl. Explanation: Hydrochloric acid is a strong acid and it is considered to completely dissociate in water under the following equation: H Cl(aq) + H 2O(l) → H 3O+(aq) +Cl−(aq) The equilibrium constant Ka is written as: Ka = [H 3O+][Cl−] H Cl nio pre market stock price today
