Ph of hydrogen iodide
WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. … WebHydrogen peroxide reacts with permanganate ion in acidic solution according to 5 H 2 O 2 + 2 MnO 4-+ 6 H+ → 2 Mn2+ + 5 O 2 + 8 H 2 O A permanganate titrant serves well for the determination of ...
