Use the table below to answer the following questions Name of acid Acetic Acid (HC2H302) Formic Acid (HCO2H) Nitrous Acid (HNO2) Hydrofluoric Acid (HF) Hydrocyanic Acid (HCN) Lactic acid (HC3H503) Ka value 1.8 x 10-5 1.8 x 104 pKa Which is the strongest acid? Why? 4.6 x 104 3.5 x 10-5 Which is the weakest acid? 4.9 x 10-10 1.4 x 104 Why? The larger the Ka the. (stronger/weaker) the acid. The smaller the pKa the (stronger/weaker) the acid. Since a weak acid dissociates incompletely setting up an equilibrium what method could you think of that you could use to determine the concentration of [H30*] ions given the initial concentration of the acid and its Ka?
