검증된 단계별 안내1
Understand the definition of a Brønsted-Lowry acid: A Brønsted-Lowry acid is a substance that can donate a proton (H⁺) to another substance.
Examine each compound to determine if it can donate a proton. Start with H2SO4: This compound is sulfuric acid, a well-known strong acid that can donate protons.
Next, consider HCl: Hydrochloric acid is another strong acid that readily donates a proton.
Now, look at CH3COOH: Acetic acid, which is a weak acid, can still donate a proton, thus qualifying as a Brønsted-Lowry acid.
Finally, evaluate NH3: Ammonia is a base that tends to accept protons rather than donate them, which means it does not fit the definition of a Brønsted-Lowry acid.
