Ionization constant of weak acid is 10 -4
WebHydrofluoric acid has a Ka value of 6.3 times 10 to the negative fourth, and acetic acid has a Ka value of 1.8 times 10 to the negative fifth. Since both of these have Ka values less than one, they're both considered to be weak acids. However, the higher the Ka value, the stronger the acid. WebThe conjugate acid and conjugate base are represented as HA and A−, respectively. [HA]= Mheormect M[A−]=incerrect ]M; Question: Calculate the pH of a 0.0654M anilinium chloride solution. Refer to the table of ionization constants. incorrect anilinium chloride Calculate the concentrations of the conjugate acid and base at equilibrium.
