Name CHM 1202 Titrations and Polyprotic Acids- Reading Guide Polyprotic Acids (section Polyprotic acids contain more than one ionizable per molecule. For all polyprotic acids, a ionization process occurs. Give the chemical equation for the first and second ionization of hydrosulfuric acid, H,S. First ionization: HS (aq) + H20 (1) Second ionization: In the above example, is the dominant producer of H,0*, and thus [H0') = Titration Curves (section Refer to Figure 14.23 to sketch the following titration curves.

Strong Acids and [H'] (and pH) The pH of a strong acid is the concentration of the strong acid. 1.OM HCI makes 1.OM H. Except H2SO4. Its pH is a little lower than that because: H2SO4(aq) H+ (aq) + HS07 (aq) Strong acids generally have K.>>1. We assume K = . The HSO, is a weak acid: HSO2 (aq) + H+ (aq) + S0 - Ka = 1.2 * 10-2 Weak Acids and [H+] (and pH) These are weak electrolytes....
