Question: 1 / 400

What happens when a Bronsted-Lowry acid donates a proton?

It becomes a conjugate acid

It transforms into a conjugate base

When a Bronsted-Lowry acid donates a proton, it transforms into a conjugate base. The Bronsted-Lowry theory defines acids as proton donors. When the acid loses a proton (H⁺), it effectively decreases its positive charge or acidic character. The species that remains after the proton donation is known as the conjugate base. For example, when hydrochloric acid (HCl) donates a proton, it becomes chloride ion (Cl⁻), its conjugate base.

Understanding this transformation is fundamental to acid-base chemistry, as it helps in predicting the outcome of reactions in which acids and bases interact. The concept of conjugate acids and bases is crucial in determining the strength and behavior of acids and bases in various chemical reactions.
