So it will be a strong acid because as the value of ph decrease, so acidity of the solution will be increased. C6H5NH3+, conjugate base is a weak base, therefore it is potentially acidic NO2-, conjugate acid is a weak acid, therefore the salt is also potentially basic However, since the Ka > Kb, the solution must be acidic So it has both nature acidic on basic in its constituent, it will act as a neutral soul. Creative Commons Attribution/Non-Commercial/Share-Alike. Explain. In case of acetate ion, its conjugate acid CH3COOH, while definitely a relatively 'weak' acid', isn't weaker than water, so its conjugate base is a weak base. Due to this we take x as 0. conjugate acid-base pair, Ka times Kb is equal to Kw, the ionization constant for water. Become a Study.com member to unlock this answer! = 2.4 105 ).
