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....

a) Set up an ICE table and calculate the pH of a solution that is 0.150 M propanoic acid, HC3H5O2. Ka = 1.30 x 10-5 for this weak acid. Calculate the % dissociation and justify whether or not "x" can be neglected. b) Another solution is 0.150 M of the conjugate base, sodium propanoate (NaC3H5O2). Calculate pOH and then pH for this basic solution. Use Ka from part (a). c) What would the pH of the acidic solution in part...
