• Hard acids are small, highly charged, and less polarizable.

• Hard bases are also small, highly electronegative, and less polarizable.

• Therefore, hard–hard interactions are most stable.

Example:

• Hard acid: H⁺, Al³⁺

• Hard base: F⁻, OH⁻

Rule to remember:
Hard acid → Hard base
Soft acid → Soft base
