Answer :
H3O+ is present in aqueous solutions with a concentration of 8.8 1012 M at 25 °C. Determine the amount of OH present. Please include significant digits in your response. OH ([OH]) concentration: Take water's ability to ionize itself as an example. 2 H2O(aq), H3O+(aq), and OH (aq)
Kw = [H3O+] [OH] = 1.0 1014 [OH] = 1.0 1014 / [H3O+][OH] = 1.0 1014 / 8.8 1012 [OH] = 1.1 103 M is the equilibrium constant for this reaction.
How much H3O+ is present in water?
In pure water, there are 10-6mol dm-3 H3O + ions present.
How is the pH of a solution determined using H3O?
The hydronium ion concentration in moles per liter must be known in order to compute the pH of an aqueous solution (molarity). After that, the pH is determined using the formula pH = - log [H3O+].
