For the autoionization of water at 25°c
WebOct 12, 2024 · The autoionization of water yields the same number of hydronium and hydroxide ions. Therefore, in pure water, [ H 3 O +] = [ OH −]. At 25 °C: (12.2.2) K w = [ H 3 O +] [ OH −] = [ H 3 O +] 2 + = [ OH −] 2 + = 1.0 × 10 − 14 So: (12.2.3) [ H 3 O +] = [ OH −] = 1.0 × 10 − 14 = 1.0 × 10 − 7 M WebC) water autoionizes only to a very small extent D) the autoionization of water is exothermic C) water autoionizes only to a very small extent Which one of the following statements regarding Kw is false? A) pKw is 14.00 at 25 °C. B) The value of Kw is always 1.0 × 10-14. C) Kw changes with temperature.
