A nitrous acid buffer solution contains 0.88 M nitrous acid (HNO2) and 0.66 M of its conjugate base (NO2â). If a chemist adds 0.13 mol of hydroiodic acid (HI), a strong acid, to 0.50 L of the buffer solution, what will be the final pH of the solution? (The pKa of HNO2 is 3.25. Assume the volume of the added HI is negligible.)
