WebOct 25, 2015 · Since your solvent is itself water, it makes no difference whether you use $\ce{H+}$ or $\ce{H3O+}$. $\ce{H3O+}$ is basically the hydrated form of $\ce{H+}$. If you know, the oxygen atom in water contains two lone pairs. When it donates one of the lone pairs to the hydrogen atom which doesn't have any electrons, you get $\ce{H3O+}$. So, 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 ?

WebMar 13, 2024 · pH = −log[H +] or pH = − log[H 3O+] It is the same equation anyways, as water can dissociate two ways. Since the hydrochloric acid has a concentration of 0.34 M, that … WebMar 10, 2024 · The hydronium ion concentration can be found from the pH by the reverse of the mathematical operation employed to find the pH. [H3O+] = 10-pH or [H3O+] = antilog (- pH) Example: What is the hydronium ion concentration in a solution that has a pH of 8.34? On a calculator, calculate 10-8.34, or “inverse” log ( – 8.34). WebHow do pH and pKa relate? The pH of a solution is directly related to the pKa of a solution via the Henderson-Hasselbach equation, pH = pKa +log( [A−] [H A]) Let's do an example: What is the pH of a 1-L solution of 0.12M of N H 4Cl to which 1 L of 0.03M of N aOH was added ( pKa of N H + 4 is 9.25[1] )?
