Consider the titration of 40.0 mL of 0.200 M HClO4 by 0.100 M KOH. Calculate the pH of the resulting solution after the following volumes of KOH have been added. a) 0.0 mL b) 10.0 mL

An analytical chemist is titrating 144.6 mL of a 0.6600 M solution of benzoic acid (HC H,CO,) with a 0.8400 M solution of KOH. The p K, of benzoic acid is 4.20. Calculate the pH of the acid solution after the chemist has added 54.06 mL of the KOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of KOH solution added. Round your answer to 2 decimal places. pH

1. A buffer solution contains 0.419 M of ammonium chloride and 0.221 M of ammonia.If 0.0293 moles of sodium hydroxide are added to 150 mL of this buffer, what is the pH of the resulting solution? (Assume that the volume does not change upon adding sodium hydroxide.) 2. A buffer solution contains 0.286 M of ammonium chloride and 0.472 M of ammonia. If 0.0620 moles of nitric acid are added to 250 mL of this buffer, what is the pH of the resulting solution? (Assume that the volume does not change upon adding nitric acid.)
