Formule h2so4
WebNov 7, 2024 · I have a solution which has [ H X 2 S O X 4] = 0.915M (I assume [ H X +] = 1,830 M). While H X 2 S O X 4 is a strong acid, H S O X 4 X − is not ( p K a around 2). So your pH should be about zero, and you might not need to use the Hammett acidity at all. Share Improve this answer Follow answered Nov 7, 2024 at 14:34 Karsten ♦ 35.4k 7 60 152 WebH2SO4 . 2.
