Practice: Write the formula of the conjugate base for the following compound:
H2Se
In 1923, Johannes Brønsted and Thomas Lowry developed a new set of definitions for acids and bases.
According to Brønsted and Lowry, an acid was classified as a proton donor while a base was a proton acceptor.
Concept #1: Discussing Brønsted – Lowry Acids and Bases.
Example #1: Write the formula of the conjugate base for the following compound: HSO4-
Example #2: Write the formula of the conjugate acid for the following compound: V2O52-
Practice: Write the formula of the conjugate base for the following compound:
H2Se
Practice: Write the formula of the conjugate for the following compound:
NH2NH2
Brønsted – Lowry acid and base reactions create products that are conjugates of the reactants.
Example #3: Identify the acid, base, conjugate acid and conjugate base in the following reactions:
HF (aq) + H2O (aq) ⇌ F – (aq) + H3O+ (aq)
Example #4: Identify the acid, base, conjugate acid and conjugate base in the following reactions:
CN – (aq) + H2O (aq) ⇌ HCN (aq) + OH – (aq)
Practice: Which of the following is a Bronsted-Lowry acid?
Practice: Determine the chemical equation that would result when carbonate, CO32-, reacts with water.
