Q5) In the exercise, Bronsted-Lowry Acids and Bases, it was shown that after on acid has given up its proton, it is capable of getting back that proton and acting as a base, conjugate base is what is left after an acid gives up a proton. The stronger the acid, the weaker the conjugate base. The weaker the acid, the stronger the conjugate base.
