WebThe proton donor is a Brønsted-Lowry acid, and the proton acceptor is the Brønsted-Lowry base: H+(aq) + OH−(aq) → H2O (ℓ) (BL acid) (BL base) Thus H + is an acid by both definitions, and OH − is a base by both definitions. Ammonia (NH 3) is a base even though it does not contain OH − ions in its formula. WebAcidity – Qualitative perspective • One compares the structural stability of the conjugate base to determine which is a stronger acid • Stronger acids have more stable conjugate bases • When an acid loses a proton, it forms the conjugate base, which has a lone pair of electrons that resulted from the lose of H+ • To determine the stability of a conjugate …
