Ph of hydrogen iodide
WebNov 15, 2014 · What was the p H of the new 72.0 m L solution? My solution: Using the Henderson–Hasselbalch equation 4.88 = − log ( 6.3 ⋅ 10 − 5) + log ( 0.10 − x x), x = 0.0173 m o l Amount of conjugate base in 70.0 m L is 0.0173 × 70 / 1000 = 1.211 ⋅ 10 − 3 m o l Amount of H I added is 4 ⋅ 10 − 3 m o l.
