Nested Domains of Generality Among the Three Theories

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

The three theories nest by generality: every Arrhenius pair is Brønsted-Lowry, every Brønsted-Lowry pair is Lewis, but broader theories classify reactions the narrower ones cannot.

Show

BF3 accepting ammonia's electron pair is Lewis chemistry with no Brønsted-Lowry or Arrhenius description available.

Watch for

No theory here is "the correct" one; each fits the scope of reaction it was built to describe.
