A Brønsted-Lowry acid is a substance that can donate a proton ($H^+$) to another substance. It is one-half of the Brønsted-Lowry acid-base theory, which focuses on proton transfer reactions.
5 Must Know Facts For Your Next Test
A Brønsted-Lowry acid must have at least one removable proton ($H^+$).
The strength of a Brønsted-Lowry acid is determined by its tendency to donate a proton.
In aqueous solutions, common examples include $HCl$, $H_2SO_4$, and $CH_3COOH$.
A conjugate base is formed when a Brønsted-Lowry acid donates a proton.
The concept extends beyond aqueous solutions and includes gas-phase and non-aqueous reactions.
