What is the chemical equation that represents the weak acid Acid-Base Reaction Problem - BrainMass the ionic bonding makes sense, thanks. The Bronsted-Lowry theory of acids and bases describes a transfer of ionized hydrogen atoms (protons) from acids to bases in an aqueous solution. OneClass: Aniline hydrochloride, (C6H5NH3)Cl, is a weak acid. (Its Is SbCl5 ( Antimony pentachloride ) polar or nonpolar ? The list of strong acids is provided below. ; Brnsted-Lowry theory says that acid can donate protons while a base can accept them. so we write: Kb is equal to concentration of our products over concentration of our reactives. Since a very strong acid has a very weak conjugate base, the chloride ion don't really take protons from water, thus it does not affect the pH of the solution, we thus do not include it into the equation.
