A buffer solution contains 0.68 mol of hydrogen peroxide (HOOH) and 0.76 mol of sodium hydrogen peroxide (NaOOH) in 1.20 L. The Ka of hydrogen peroxide (HOOH) is Ka = 2.4e-12. (a) What is the pH of this buffer? pH = (b) What is the pH of the buffer after the addition of 0.56 mol of NaOH? (assume no volume change) pH = (c) What is the pH of the original buffer after the addition of 0.30 mol of HI? (assume no volume change) pH =
