Khan Academy offers a comprehensive guide on Bronsted-Lowry acid-base theory, explaining the concepts of acids and bases in chemistry.
Organic chemistry. Course: Organic chemistry > Unit 5. Lesson 2: Nucleophilicity and basicity. Nucleophilicity (nucleophile strength) Nucleophilicity vs. basicity. Science>. Organic chemistry>. Substitution and elimination reactions>.
The relative strength of an acid can be predicted based on its chemical structure. In general, an acid is stronger when the H–A bond is more polar. Acidity is also greater when the H–A bond is weaker and when the conjugate base, A⁻, is more stable.

For the titration of a weak base with a strong acid, the pH curve is initially basic and has an acidic equivalence point (pH < 7). The section of curve between the initial point and the equivalence point is known as the buffer region.
Learn how to name and identify acids and bases from their formulas and physical observations in the lab. Discover the distinction between strong and weak electrolytes and their significance in acid-base chemistry, then finish with uncovering the secrets behind the pH scale!
Base and nucleophiles are similar yet different, they can change the course of a reaction. Let's solve some problems to differentiate bases from nucleophiles.
