Any substance which accepts H+ is base favours the concept___________________?
Correct answer: A. Lowrys
- A. Lowrys
- B. Lewis
- C. Arrhenius
- D. None of these
Explanation
The Brønsted-Lowry concept defines a base as a proton, H+, acceptor. The Lewis concept instead defines a base as an electron-pair donor, while the Arrhenius concept concerns production of OH- in water. Students may choose Lewis because many bases donate electron pairs, but accepting H+ specifically identifies the Brønsted-Lowry concept.

About Buffer Solutions
Buffer solutions resist changes in pH when small amounts of acid or base are added, using a weak acid and its conjugate base or a weak base and its conjugate acid. Work includes buffer action, the common-ion effect, Henderson-Hasselbalch calculations, buffer capacity, and the difference between acidic and basic buffers.
