Ph of hydrogen iodide
WebJul 1, 2002 · Sodium iodate in the presence of NaOH disproportionates to iodide and orthoperiodate according to the reaction NaIO3 + 3NaOH → 1/4NaI + 3/4Na5IO 6 + 3/2H2O. The process begins at ∼270°C and ... WebThe pH will be less than 7 (not neutral) for a weak acid and is typically greater than the value for a strong acid. Notice that exceptions occur. For instance, for a 1 mM solution, the pH of hydrochloric acid is 3.01, while the pH of hydrofluoric acid is very low, with a value of 3.27 for a 1 mM solution.
