A student prepares a 100.0-mL buffer solution that is 0.200 M in hydrofluoric acid and 0.200 M in sodium fluoride. How many grams of sodium hydroxide should be added to the buffer solution to change its pH to 4.00? (Assume no volume change upon adding the sodium hydroxide). I'm seeking the detailed work in finding the solution to this problem. Many thanks!
