In a solution of pure water, the dissociation of water can be expressed by the following: h2o(l) + h2o(l) ⇌ h3o+(aq) + oh−(aq) the equilibrium constant for the ionization of water, kw, is called the ion-product of water. in pure water at 25 °c, kw has a value of 1.0 × 10−14. the dissociation of water gives one h3o+ ion and one oh− ion and thus their concentrations are equal. the concentration of each is 1.0 × 10−7 m. kw = [h3o+][oh−] kw = (1.0 × 10-7)(1.0 × 10-7) = 1.0 × 10-14 [h3o+][oh−] = 1.0 × 10-14 a solution has a [oh−] = 3.4 × 10−5 m at 25 °c. what is the [h3o+] of the solution? answer 2.9 × 10−9 m 2.9 × 10−15 m 3.4 × 109 m 2.9 × 10−10 m i don't know yet
