Ionic Equilibria: Acids, Bases & pH
Narrated lesson · press play
Acids and bases are best understood as an equilibrium of proton transfer. Learn the Brønsted-Lowry theory and conjugate acid-base pairs, why strong and weak acids differ in the extent of their dissociation, what pH really measures, and how to calculate the pH of a strong acid.
What you'll learn in this lesson
By the end you should be able to (NSSCAS Chemistry (AS Level) 2.3.2):
- Explain and use the Brønsted-Lowry theory of acids and bases
- Identify conjugate acid-base pairs (acid-1/base-1, acid-2/base-2)
- Explain the difference between strong and weak acids and bases in terms of extent of dissociation
- Relate pH to hydrogen ion concentration
- Calculate [H⁺(aq)] and pH for strong acids
