Acid Strength & Conjugate Base Stability | Understanding Acid–Base Strength
Watch on YouTube →
Overview
Acid strength depends on how stable the conjugate base is after an acid loses a proton: a more stable conjugate base corresponds to a stronger acid. The lesson centers on this relationship as the basis for comparing acid–base strength.
Key takeaways
- An acid forms its conjugate base by donating a proton, H⁺.
- Greater conjugate base stability corresponds to greater acid strength.
- Conjugate base stability provides a practical criterion for comparing the strength of different acids.
- A comparatively unstable conjugate base indicates a weaker acid because proton donation is less favorable.

Acid Strength and Conjugate Base Stability
- The central concept is the relationship between an acid's strength and the stability of its conjugate base.
- A conjugate base forms when an acid donates a proton, H⁺.

Why a Stable Conjugate Base Signals a Stronger Acid
- Formation of a more stable conjugate base makes proton donation more favorable.
- Acids that produce less stable conjugate bases are comparatively weaker proton donors.

Using Conjugate Base Stability to Compare Acids
- Compare acids by considering the relative stability of the conjugate bases formed after H⁺ loss.
- The key comparison runs in the same direction: greater conjugate base stability corresponds to greater acid strength.
