Calculate the volumes of 0.200 M hydrocyanic acid, HCN (Ka = 4.9 x 10–10) solution, and 0.200 M of sodium cyanide, NaCN, solution needed to prepare 100.0 mL buffer solution with pH = 9.5
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!
A buffer solution contains 0.58 mol of hydrocyanic acid (HCN) and 0.68 mol of sodium cyanide (NaCN) in 3.00 L. The Ka of hydrocyanic acid (HCN) is Ka = 4.9e-10. (a) What is the pH of this buffer? pH = (b) What is the pH of the buffer after the addition of 0.46 mol of NaOH? (assume no volume change) pH = (c) What is the pH of the original buffer after the addition of 0.23 mol of HI? (assume...
