Question

Q;From each of your two pH measurements for acetic acid calculate the dissociation constant of acetic acid. Which is more reliable? When you dilute 1.0 M acetic acid to 0.1 M, did [H3O+] change by a factor of 10? Explainю

Answer 1

No pH won't change with a factor of 10 because it is not completely dissociated acid. it depends upon degree of dissociation.

CH₃COOH $=$ CH₃COO^- + H⁺

K = [CH₃COO^-][H⁺]/ [CH₃COOH]
