In the Brønsted-Lowry concept, a conjugate base of an acid is formed by
Again of a proton by the acid
Bloss of a proton by the acid
Ctransfer of an electron
Dloss of OH⁻
Answer & Solution
Correct answer: B. loss of a proton by the acid
1. A Brønsted-Lowry acid donates a proton.
2. The species left after proton loss is its conjugate base.
3. Example: HCl → H⁺ + Cl⁻; Cl⁻ is the conjugate base.
