QUESTION 2 Choose the correct acid ionization constant (ka) expression for hydrochloric acid. Hint: write out the chemical equation for the ionization. [H,0*[cr] [H*] Ka= [H30* [cr] Ka = [HCI] [H*] Ka- H30 Icr] [HCI] O Ka [H30 Icr] QUESTION 3 Why does a buffer solution require a weak acid/base conjugate pair, as opposed to a strong acid, and its conjugate? O A strong acid will only partially dissociate, suggesting that the conjugate base is really strong and will not neutralize any additional H+ ions. O A strong acid will completely dissociate, suggesting that the conjugate base is really strong and will not neutralize any additional Ht ions. A strong acid will only partially dissociate, suggesting that the conjugate base is really weak and will not neutralize any additional H* ions. O A strong acid will completely dissociate, suggesting that the conjugate base is really weak and will not neutralize any additional H+ ions.
