2. Calculate the pH of the following aqueous solutions:
a) a solution that is 0.15 M HCl and 0.10 M Ba(OH)2
b) a solution that is 0.20 M CH3COOH (Ka = 1.8 x 10-5) and 0.25 MNaOH
c) a solution that is 0.20 M NH3 (Kb = 1.8 x 10-5) and 0.05 MHI.
3. 50.0 mL of a solution of 0.15 M NaCl is mixed with 25.0 mL of asolution of 0.30 M KBr. What are the final concentrations ofNaCl(aq) and KBr(aq)?
