Conjugate Acid
Definition
A conjugate acid is a species formed by the reception of a proton (H+) by a base—in other words, it is the base with a hydrogen ion added to it.
Analogy
Think of a conjugate acid as someone who has just received an extra dollar (proton). Before they had the dollar, they were just themselves (the base), but now that they've received this extra dollar, they're slightly different and have more purchasing power (they've become an acid).
