WebJan 24, 2016 · The pH is close to 7. So the hydronium ion concentration of water can't be neglected. [H3O+fro water + H3O+ from acid][OH-]=10^-14 ... Calculating pH when weak base is added to an strong acid. 0. Finding the pH of a mixture of weak acid and strong base. 1. Discrepancies in using pOH vs pH to solve H+/OH- concentration change … WebThe only equilibrium concentrations we are concerned with when calculating the pH of a solution are the concentrations of H3O+ ions, OH-ions, weak acids and weak bases. So here we have [H3O+] = n/V = 0.01 moles / 0.3 L = 0.033 M. Note we had to convert back to concentrations from moles. The volume of the solution is 0.3 L ft wayne vet clinic

WebChemistry questions and answers. 1. Calculate the [H3O+], [OH−],pH, and pOH of a 0.386M ethylamine (C2H5NH2) solution. The Kb of C2H5NH2 is 5.6×10−4 2. What is the percent ionization of propionic acid (CH3CH2COOH) in a solution that is 0.45MCH3CH2COOH ? WebChemistry questions and answers. 1. Calculate the [H3O+], [OH−],pH, and pOH of a 0.386M ethylamine (C2H5NH2) solution. The Kb of C2H5NH2 is 5.6×10−4 2. What is the … Web(H3O+)(OH-) (H2O) **This is a legal and useful approach. Remember, the K is an algebraic, numerical constant. Because the activity of water is 1: KaKb = (H3O+) + (OH-) = Kw = 10-14 Where Kw is the equilibrium constant water. This relationship allows the calculation of either Ka or Kb if the other is known by: pH + pOH = pKw = 14 gilford road pharmacy
