Activity 11 This problem is on how to determine the pH of a salt. The salt is NaCIO. Find the pH of a solution that is 0.31 M NACIO. To do this: • Figure out which ions form in solution and determine if they are acidic or basic or neutral Write out the hydrolysis reaction. • Set up the equilibrium problem. Figure out if x is negligible. You will need the value of Kb for Cio. This is not in the table of Kb's. Use this method: Kw K,(conjugate base) = So K, (CIO") = K¸(acid) K (HCIO) Solve for x in the equilibrium problem. (Is x negligible in the denominator?) x = [OH']. Use this to get the pOH and then the pH.
