But we should also know that when we multiply the numerator and denominator of a fraction by the same number or expression, we end up with a fraction that is equivalent to the original fraction. Conjugate acids and bases are Bronsted-Lowry acid and base pairs, determined by which species gains or loses a proton.When a base dissolves in water, the species that gains a hydrogen (proton) is the base's conjugate acid.
