Study Notes

Brønsted–Lowry Acid–Base Theory

A conjugate acid is the species that forms when a base accepts a proton (H+).
A conjugate base is the species that forms when an acid donates a proton (H+).
According to the Brønsted–Lowry theory, acids are species that donate a proton (H+), while bases are species that accept a proton (H+).
A hydrogen cation is represented by the symbol H+.
Water (H2O) can be a conjugate base depending on the acid–base theory used.
According to the Brønsted–Lowry theory, an acid is a species that donates a proton (H+).
A conjugate base can be an anion, such as Cl-, which is formed when a hydrogen chloride (HCl) donates a proton.
The symbol H+ represents a proton, which is a hydrogen cation.
