Ph of oh
The hydroxide ion is a natural part of water because of the self-ionization reaction in which its complement, hydronium, is passed hydrogen: H3O + OH ⇌ 2H2O The equilibrium constant for this reaction, defined as Kw = [H ][OH ] WebbpH=10.11 3. Finally, we can calculate the [H+]. Click the second function button on your scientific or graphing calculator then click the log button. Then, type in the negative sign, …
